What is consciousness? What is the mind? What is the self? Why do we suffer — and is there a way through it that doesn't require pretending everything is fine? These are the questions this podcast begins with. Hosted by Nicky Grimsdale - Vedic educator, yoga teacher and practitioner with over 20 years of study in Indian philosophy including time living and practising in India. This series moves through the great schools of Vedic and Indian spiritual traditions with special emphasis on Advaita Vedanta and Yoga along the way. Nicky approaches contemplative thought with clarity, depth, relatability and a genuine respect for the intelligence of the listener. Alongside solo episodes, the podcast features conversations with teachers, thinkers, and practitioners from across the traditions and other complementary schools of thought. The approach is both personal and rigorous. This isn't wellness content. It isn't spirituality made palatable. It is a genuine investigation — informed by years of practice, study, and a deep engagement with the lineages of Indian philosophy. What you'll find here: Indian philosophy that holds up academically and lands in the body. Ancient teachings explained with honesty, humour, and the occasional analogy that makes a thousand-year-old idea feel like something you already knew but couldn’t find the words. For the yoga student who suspects there's more to the tradition than postures. For the meditator who wants to understand the philosophical framework underneath the practice. For the curious mind who finds consciousness and the exploration of the Self genuinely interesting.
"What Is the Mind? What Are Thoughts? What Is Meditation?" What is your mind, actually? Not what it contains - the thing itself. Where does it begin, where does it end, and is it even the same thing as your brain? This episode takes one of the most familiar and least examined parts of your entire existence and looks at it from four genuinely different angles: what modern neuroscience says, and where it runs out; what the Samkhya-Yoga tradition's precise fourfold map of the mind reveals; what Buddhism's teaching of no-self adds that the other frameworks miss; and finally, what Advaita Vedanta says the mind actually is, once you stop assuming it's separate from consciousness altogether. Each framework earns its own space and its own respect. By the end, the four aren't presented as competing theories to choose between, but as different instruments - each doing something genuinely useful, each building toward the next. You'll come away with a concrete, usable understanding of what a thought actually is, what meditation is doing to your mind at each stage of practice, and a simple, practical distinction - I am anxious versus there is anxiety, and I am aware of it - that you can test in your own experience immediately. Grounded, clear, and built for genuine practice rather than abstract theory. In this episode: Where neuroscience's account of the mind is strong, and exactly where it runs out The hard problem of consciousness, explained simply Samkhya's fourfold map of the mind — manas, buddhi, ahamkara, chitta What a thought actually is: the vritti, and why citta vritti nirodha doesn't mean stopping thought Meditation as understood through Yoga, Buddhism, and Advaita - three different aims, three different methods The practical distinction between being anxious and being aware of anxiety How the three traditions relate to and build on each other, without collapsing into one A guided moment to actually try self-enquiry, live, while listening RECOMMENDED RESOURCES FOR DESCRIPTION The Yoga Sutras of Patanjali — Edwin Bryant translation (the foundational dualist meditation text) I Am That — Nisargadatta Maharaj (the most direct account of the Advaita approach to mind) The Nature of Consciousness — Rupert Spira (mind and awareness through Advaita) Tantra Illuminated — Christopher Wallis (Kashmir Shaivism's account of mind and thought) The Mind Illuminated — Culadasa (John Yates) (the most comprehensive contemporary integration of Buddhist meditation and neuroscience) What the Buddha Taught — Walpola Rahula (the Buddhist account of mind and no-self) Being No One — Thomas Metzinger (rigorous philosophical neuroscience on the self-model — for the philosophically adventurous) Swami Sarvapriyananda on the Antahkarana — YouTube, Vedanta Society of New York (exceptional lecture on the Samkhya model of mind)
The waking, dreaming, and deep sleep states and the fourth that underlies them all Every night, without exception, you disappear completely and come back. What actually happens in between? This episode takes the most ordinary thing you do every single day and turns it into one of the most precise philosophical investigations available to a human being. Drawing on the Mandukya Upanishad - the shortest of the principal Upanishads at just twelve verses, and one of the most rigorously argued texts in the entire Vedantic tradition - Nicky walks through the teaching of Avastha Traya : the investigation of waking, dreaming, and deep sleep, and what remains present through all three. You'll be guided through each state in turn - the world you take to be obviously real, the dream world your own mind constructs and then completely believes, and the deep sleep state where both dissolve entirely and yet something is still there to report on it. From there, the episode introduces turiya , not a fourth state, but the awareness underlying all three, present and unchanged through everything. Along the way: an honest engagement with the sceptic's strongest objections, Gaudapada's radical teaching of ajata vada , and the elegant mapping of the whole teaching onto the sound of AUM. This episode is intimate rather than academic in tone - less a lecture, more an invitation to look at something you already have direct access to, tonight, in your own bed. In this episode: The three states — waking ( jagrat ), dreaming ( svapna ), and deep sleep ( sushupti ) Why the Mandukya Upanishad uses your own nightly experience as its method, not abstract argument Gaudapada's Karika and Shankara's commentary - the layered philosophical foundation What deep sleep actually reveals about the nature of the self Turiya - the fourth, and why it isn't a state at all The sceptic's case, addressed directly and without dismissal Gaudapada's Ajata Vada - the doctrine of non-origination How AUM maps onto the entire teaching, sound by sound Why this matters: suffering, the fear of death, and the nature of the present moment References and further reading: The Mandukya Upanishad - trans.

Episode 1 and 2 gave us the map of Indian philosophy. Now - what do you actually do with it? This is the final episode in The Ground Tone , and the one where philosophy finally lands in the body. Across the first two episodes, Nicky built the full philosophical architecture - the six schools of Indian philosophy, the difference between dualist and non-dual thought, and the depths of Advaita Vedanta. This episode answers the practical question every serious student eventually asks: how do the actual practices - yoga, meditation, chanting, ritual, service - relate to all of it? Most people treat these as a menu of interchangeable options. This episode makes the case that they're something far more interesting: instruments, each one built for a different part of the same composition. Karma yoga, bhakti, hatha yoga, and tantra are each explored in depth - what they actually are, where they come from, and what they're specifically designed to do - before the episode moves into an extended and deeply personal exploration of Kashmir Shaivism, one of the most elegant and inclusive philosophical traditions Nicky has encountered, and a school she returns to again and again. The episode closes with the synthesis the whole series has been building toward: how the philosophical schools, the nastika traditions, and the practical instruments all fit together as facets of one whole - and why understanding that whole matters, not as an intellectual exercise, but as the foundation for genuine discernment, a more embodied practice, and a life lived with more grace and less confusion. In this episode: Why the practices are instruments, not a menu of interchangeable options Karma yoga - action without the ego's ownership of the outcome Bhakti yoga - devotion, the symbology of the deities, and love as the natural expression of non-dual understanding Hatha yoga - its tantric roots, and why it's a world away from a modern studio class Tantra - the philosophy that refuses to leave anything out Kashmir Shaivism - spanda, pratyabhijna, and why Nicky keeps returning to this school How the philosophical schools and the practical instruments form one integrated whole The final synthesis of the three-part series - and where it all points References and further reading: The Bhagavad Gita - trans.

The witness is not the destination. It's the doorway - and Advaita Vedanta shows you what's on the other side. This episode is the philosophical heart of the 3 part series, and the most personal. Picking up from Part 1, Nicky goes deep into the distinction that changed everything in her own practice: the difference between dualist and non-dual philosophy. Not as an abstract debate, but as a live question with real consequences for how you experience your life, your mind, and your sense of self. Using a simple but precise analogy drawn from classical Advaita - a shadow in a dim room mistaken for a figure - the episode shows the fundamental difference between the Samkhya-Yoga approach (developing a stable witness that stands apart from experience) and the Advaitic approach (investigating the very nature of the witness itself, and finding something that was never what you assumed). The difference is not subtle. One is a practice of skilful relationship. The other dissolves the need for a relationship altogether. From there, the episode moves through the three major sub-schools of Vedanta - Madhvacharya's devotional Dvaita, Ramanuja's elegant Vishishtadvaita, and Shankara's radical Advaita - showing how three great minds reading the same foundational texts arrived at the full spectrum from dualism to complete non-dualism. And it introduces the ocean and wave teaching - one of the most precise and enduring analogies in the entire tradition — to show what non-dual philosophy is actually claiming about the nature of consciousness, experience, and what you are. The episode closes with the three stages of Vedantic learning - sravana, manana, nididhyasana - and a reframe that changes the purpose of practice entirely: not climbing a ladder toward liberation, but cleaning a lens through which what was always already present becomes more clearly visible. Intimate, philosophical, and pointing at something you can verify right now. In this episode: The personal itch that the witness-based practice couldn't resolve Dualist vs non-dual philosophy - what the distinction actually means in daily life The shadow-in-the-room analogy - and why turning on the light changes everything The ocean and the wave - consciousness, identity, and what you're actually made of Dvaita, Vishishtadvaita, and Advaita Vedanta - three sub-schools, one foundational text Madhvacharya, Ramanuja, and Adi Shankaracharya Sravana, manana, nididhyasana - the three stages of Vedantic learning Avidya — why the problem isn't lack of experience but a specific misperception The ladder and the lens - what changes when the purpose of practice changes What consciousness, happiness, and integration actually look like from a non-dual perspective References and further reading: I Am That - Nisargadatta Maharaj The Nature of Consciousness - Rupert Spira Who Am I? - Ramana Maharshi (short, essential, available free online) The Vivekachudamani - Adi Shankaracharya, trans.

The Ground Tone — Part 1 of 3 You've may have heard the Vedic teachings. But do you know where they come from and what they actually mean? This episode is the map that changes everything. In yoga studios, on social media, in wellness spaces - fragments of some of the most sophisticated philosophical thought in human history float around without context, without lineage, and often without their original meaning intact. This episode gives you that context. Not to replace your practice, but to deepen it completely. Nicky introduces the Sad-darshana (the six classical schools of Indian philosophy) and explains how six extraordinarily different systems of thought all emerged from the same ancient source: the Vedas. From the atheist dualism of Samkhya to the rigorous logic of Nyaya, from the ritualism of Mimamsa to the exceptional non-dualism of Advaita Vedanta - each school is a different raga played in the same key. Understanding the difference between them is one of the most clarifying things a serious practitioner can do. The episode also covers the nastika schools - Buddhism, Jainism, and the materialist Carvaka - and why their existence tells us something important about the intellectual honesty of the tradition. Plus: why modern postural yoga is not what Patanjali was describing, where Hinduism fits in the picture, and a compelling introduction to what Vedanta is actually proposing and why it might be the most significant philosophical discovery available to a human being.
