Commentary

Krishna now introduces a key philosophical framework that will culminate in the revelation of His supreme identity as Purushottama — the Supreme Person who transcends both categories described here.

The two categories are kshara (fallible, changeable) and akshara (infallible, unchangeable). Every living entity in the material world is kshara — subject to change, transformation, and the six modifications of the body: birth, growth, sustenance, reproduction, decay, and destruction. These are the bodily changes, not changes in the soul itself, but the soul in material contact appears to undergo these transformations because of its identification with the body.

In the spiritual world, the living entities are akshara — they are eternally in their spiritual forms, unchanging, undecaying, and always in full consciousness of their relationship with the Supreme Lord. There is no birth, no death, no aging, and no disease in the spiritual realm. The souls there remain in one eternal state of blissful existence.

The word kootastha applied to the akshara beings means “standing at the summit” or “unchanging” — they are established in an unalterable state of spiritual reality. This does not mean they are static or inactive; rather, they are free from the material modifications that plague conditioned souls.

This verse sets the stage for verse 17, where Krishna will reveal that beyond both these categories — beyond the fallible and the infallible — there exists a third, supreme category: the Supreme Person Himself, who enters and sustains all worlds.
