Avyakta–Vyakta and Causality: Discrimination of Field and Knower

Bhishma said: When the inner Self enters the body, it spreads out through the “rays” of the senses and, by those sensory functions, apprehends the five objects of experience. When it departs at death, it gathers those powers back into itself and goes on—just as the sun, having risen, casts its rays in all directions, and at setting draws those very rays back into itself. Therefore embodied experience is a temporary projection of consciousness through the senses; one should not mistake sensory life for the Self, nor cling to objects as if they were permanent.

The Self is distinct from the body and senses: it ‘projects’ experience through the senses to grasp the five sense-objects, and at death it withdraws those faculties and moves on. Hence one should cultivate detachment and self-knowledge rather than identify with sensory life.
In Shanti Parva’s instruction on dharma and liberation, Bhishma explains to the listener how the jiva/inner Self operates in embodiment, using the sun’s rays as a simile for the senses spreading out during life and being gathered back at the time of departure.
