I agree with Kioma that soul is energy / spirit (part of Cosmic spirit) and it is not of any physical matter.
All senses / thoughts & experiences are controlled by intellect- sub-conscious and soul . This is beautifully explained with an analogy
with chariot in Kathopnishad . Even plato also used the same analogy with a minor difference (
plato's allegory of chariot) . But both the comparisons essentially point to describe reality how it works and should really work with seeker through this mind-body-apparatus.
