Though the soul is not active, it is conscious and is considered a doer, or an actor, or an agent of deeds. The mind is not considered as actor, because it is devoid of Consciousness, though it is responsible for activity.
यथास्वेनात्मनाऽऽत्मानं सर्वः सर्वासु योनिषु| प्राणैस्तन्त्रयते प्राणी नह्यन्योऽस्त्यस्य तन्त्रकः ||७७||
Thus, the ability to “cause” or “act” resides in the conscious and not in unconscious. The soul can independently enter any animate body. There is no other controller of soul, hence, it is considered a self controller. It is to said that the soul is free and independent to do its deeds but it is not free to get result of its deeds as per its own wish.
Here it can be understood that the control of its activities and its entry into the body is governed by the result of its deeds. The soul is absolutely free to act as it pleases. It is however obliged to enjoy the results of its own deeds. It is also free to control the mind associated with it. And the free soul, when meditates, get rid of the results of good or bad acts of its own.
Even though the soul is all pervasive, it can perceive sensations in its associated physical body through the contact of sense organs with their respective objects. (Being limited by the contacts of the bodily sense organs with their objects), the soul cannot have all sensations
When the omnipresent, supreme soul gets combined with manas and other senses, it becomes kshetragya i.e., one that has the power to go anywhere in the universe and become a knower of that body. It can perceive objects inspite of (spatial, temporal or material) obstructions.
