The inner Self, being a fragment of God, remains unchanging and immortal; it neither decays nor perishes. During the cosmic drama of Creation, the pseudo-self (Kshara Purusha), formed by the Modes of Nature, envelops the imperishable Self (Akshara Purusha). The components of the subtle body, such as the mind, intellect, and ego, which create the pseudo-self around the authentic Self (soul), are integral parts of Nature. It is this pseudo-self that engages in worldly experiences and endures suffering within the triadic realm of Nature. This pseudo-self traverses from one body to another through the cycles of rebirth, carrying with it the authentic self that remains attached to it, and yet the authentic Self (soul) remains untouched by kārmic influences. However, when the Nature-constructed covering around the authentic Self is incinerated and dissolved through spiritual practices, such as the Path of Knowledge or the Path of Loving Devotion, the genuine Self becomes liberated from the constraints imposed by the Modes of Nature, as well as the covering constructed around it. In this verse, the pseudo-self is referred to as Kshara Purusha because it is a part of Nature and thus susceptible to destruction. Conversely, the original soul is called Akshara Purusha, signifying its indestructible nature as a fragment of God. The Lord briefly introduced us to the concept of the pseudo-soul in verse 13:20.
