Even though it is located in one body when associated with the mind through physical actions, it is still present in all other bodies. Conversely, in spite of it being present in all bodies, its field of action is limited to one body alone because of its contact with the mind.
Aatma (soul) does not have a beginning, and similarly, the corpus (combination of ayu elements) also does not have a beginning. The continuity of kshetra and kshetragya is so long that it is not possible to say which came earlier (kshetra or kshetragya)
It is only he who knows things that can stand as a witness. So, all attributes, actions etc., of bhutas are witnessed by the soul (who alone is the knower of things). Things cannot be witnessed by unconscious objects (like stone).
The absolute soul is unity and singular. It does not have signs or symptoms. Since it is inaccessible, it has no sensation. It is only the samyoga purusha (24 tattvatmaka purusha) that has sensations.
