If you can observe your thoughts —
who's doing the observing?

Vedic philosophy explores this question.

I make its insights accessible.

"As close to tradition as necessary —
as accessible as possible."

Indian culture has intrigued me since I was 14 years old. Through Indian movies (Bollywood), Kīrtan, and Haṭha Yoga, it has accompanied me all my life. During my psychology studies, I stumbled upon Vedic philosophy as a tradition which is how I ended up doing what I do. I see my role as making Vedic philosophy accessible — not as an academic, but as someone who can break complex ideas down into something you can actually grasp.

My specific interest lies in the parallels between Vedic scripture and the reports of near-death experiences — a topic that has fascinated me ever since I first heard about it.

In my work I focus on Sāṃkhya and Yoga, anchored by the Bhagavad Gītā. What holds my interest is their intriguing distinction between the observer and the observed — between puruṣa and prakṛti. In the Sāṃkhya framework, consciousness is not material. It is fundamentally different from thoughts, emotions, and the body. I find this dualistic approach an especially helpful framework for describing what people touch in near-death experiences: the sense of being more than the identity we believed ourselves to be.

"The self is by nature a witness — it observes without being involved or changed."

zurūck came out of this work — an orientation platform for people who have returned from a near-death experience. It places their experience alongside what Vedic philosophy says about the mind and consciousness.

Dr. Alok Kanojia's lectures on Vedic psychology were the first access I found. What followed was an intensive period of study: Vedic psychology at the Jiva Institute. Edwin Bryant's translation of the Yoga Sūtras — all 598 pages. A study group I lead to work through the text week by week, Sūtra by Sūtra. Sanskrit at the Oxford Centre for Hindu Studies. And finally an in-depth study of the Sāṃkhya Kārikā.

Introduction

Who are you?

Most answer with what keeps changing: roles, careers, relationships. But something stays the same. When you were five, you were already you. When you were thirty, you were still you… and you'll still be you when you're eighty. Vedic philosophy has been exploring this question for millennia: Who are »you«, if everything else keeps changing? Who is this observer that can observe your thoughts, your emotions, and your identity? Or who are »you«, when you've had an out-of-body experience?

There are many different streams within Vedic philosophy that attempt to answer this question. In this talk, however, we will focus on what the dualistic Vedic tradition of Sāṃkhya/Yoga has to say about who we are — and why we keep identifying ourselves with what constantly changes.

This talk is currently in preparation. If you'd like to know when and where it takes place — stay in touch.

Foundations

Two talks. First the structure of reality based on the Sāṃkhya Kārikā — then the mechanisms that obscure it based on the Yoga Sūtras.

Who we are — and what we're not

Foundations I · Sāṃkhya Kārikā

The Sāṃkhya Kārikā is a text from the dualistic philosophical Sāṃkhya school. Its premise, just like the Buddhist school, is to permanently end human suffering by realizing who we truly are — not our thoughts, emotions, or the body. Sāṃkhya explores the answer to the question of »who we are« with a fundamental distinction: between the observer and the observed.

Sāṃkhya works with two principles: puruṣa — pure consciousness, the observer — and prakṛti — everything that can be observed, including thoughts, emotions, and the body. It provides the theoretical ground for the practice the Yoga school is built upon.

Who we think we are

Foundations II · Yoga Sūtras

Sāṃkhya describes what we are not — a complete account of the observable, prakṛti. None of it is »you«. Even if we cognitively understand the distinction between the observer (puruṣa) and the observed (prakṛti), why do we keep identifying with what we observe?

In the Yoga Sūtras, Patañjali names the reason: avidyā — ignorance. It is the persistent habit of taking ourselves to be what we observe: our identity, the ego. In Foundations II we examine the patterns (kleśas) that keep it running.

Once we understand these psychological patterns, we can discover what Yoga is actually meant to be: a system to remove ignorance (avidyā) so we can rediscover who we truly are. A system that has little to do with what we today regard as Yoga practice. The following talk introduces the various Yoga paths back to who we are, described in the Bhagavad Gītā.

These talks are currently in preparation. If you'd like to know when and where they take place — stay in touch.

The Paths

The Bhagavad Gītā describes not one path back to who we are, but four: the paths of knowledge (Jñāna Yoga), meditation (Dhyāna Yoga), action (Karma Yoga), and devotion (Bhakti Yoga).

Jñāna Yoga — Knowledge

Jñāna Yoga is the path of knowledge — the realized discernment between who we are and what we mistake ourselves to be. The Bhagavad Gītā treats jñāna as the foundation on which all the other Yoga paths rest (BG IV.33: "All action finds its conclusion in knowledge"). You have to understand what you're not in order to seek who you are.

Dhyāna Yoga — Meditation

Dhyāna yoga is the path of meditation. The Bhagavad Gītā mentions meditative Yoga as a path toward direct experience of who we are. This type of Yoga is part of the eight-limbed path (Aṣṭāṅga Yoga) described by Patañjali and systematically works on turning one's attention inward until the movements of the mind come to rest and our true being becomes visible. It is clear that of all Yoga paths, dhyāna yoga appears as the most demanding since it is often connected to renouncing the world.

Karma Yoga — Action

Karma Yoga is the path of selfless action — acting without attachment to the result. Action as an expression of our duty (dharma) rather than a tool of the ego — the identity we mistake ourselves to be. Karma yoga, rightly understood, is renunciation — not the abandonment of action, but the release of attachment to its result.

Bhakti Yoga — Devotion

Bhakti Yoga is the path of devotion — dissolving identification with the ego by devoting oneself toward something greater. The Bhagavad Gītā is the central text for bhakti and presents devotion as the path that brings one closest to the divine.
