Soul
Atman is the eternal witness behind body and mind, the Self that does not age, sicken, or die. Vaisheshika counts it as the sixth substance, host of Consciousness.
What is the Soul (Atman)?
You change constantly. Your body ages, your moods shift and your thoughts come and go. Ayurveda asks what it is in you that notices all of this change without itself changing.
Its answer is the Soul (Atman), the eternal witness behind body and mind. Atman is the Self that does not age, sicken or die. It is the substratum of Consciousness, the ground from which Consciousness arises.
In Vaisheshika philosophy, one of the schools of thought behind Ayurveda's worldview, Atman is counted as the sixth of the nine causative substances. Without the Self, consciousness is not possible.
The Core Principles of the Soul (Atman)
The Self is the eternal witness
Atman stands behind body and mind and observes them. It does not age, sicken or die, which sets it apart from everything it witnesses.
Atman is the sixth causative substance
Vaisheshika philosophy lists nine causative substances and counts Atman as the sixth. In this view, Atman is a material, causative factor of creation and the host of Consciousness.
It has two kinds
The Soul is described as eternal, universal, inferred and indivisible. It is of two kinds: the individual soul (Jivatman) and the supreme soul (Paramatman).
Consciousness depends on the Self
Atman is the substratum of Consciousness. Consciousness evolves because the soul exists, and without the Self, consciousness is not possible.
The Self is independent of body and mind
The Self can exist without the body, and it can exist without the mind. In deep sleep you forget both, yet the Self remains, and in dreams it still functions through the mind.
How the Soul (Atman) Works in Practice
Atman is not something a practitioner measures with the pulse or the tongue. It cannot be seen and it cannot be measured, yet it can be experienced, and one can merge into it.
What the concept does in practice is set the frame for everything else. Because Atman is the eternal witness, Ayurveda treats body and mind as things the Self experiences and works through, not as the whole of who you are.
Your own nightly sleep offers a simple illustration. In deep sleep you forget body and mind, yet you remain. In dreams, the Self still functions through the mind. Noticing this can help you sense the difference between the witness and what it witnesses.
The concept also explains how you know other people are conscious. Individual souls do not perceive other souls directly, but they infer their existence.
