vasamsi jirnani yatha vihaya navani grhnati naro 'parani tatha sarirani vihaya jirnany anyani samyati navani dehi"

"Just as a person casts off worn-out garments and puts on others that are new, the soul similarly casts off worn-out bodies and enters into new ones.''

This sloka illustrates the concept of the eternal soul (atman) transitioning from one physical body to another through the process of reincarnation, or transmigration of the soul. Just as we discard old clothes and wear new ones, the soul discards old bodies and takes on new ones in its journey through the cycle of birth and death (samsara).

The analogy of changing clothes helps to understand the impermanent nature of the physical body and the eternal nature of the soul. It suggests that just as we don't mourn the loss of old clothes when we acquire new ones, similarly, we shouldn't grieve over the inevitable changes in the physical body. Instead, we should recognize the soul's journey through different bodies as a natural process.

This sloka encourages us to contemplate the transient nature of the physical body and to focus on the eternal aspect of our being, the soul. It invites us to understand that the essence of who we are transcends the physical realm, and our true identity lies in the eternal soul.
