One's true identity is not this human body, but the jiva that resides within it. The jiva, also called 'atma' or soul, is eternal - it cannot be destroyed. The jiva has no gender; it is neither male nor female.
Bhagwan Swaminarayan discusses the nature of the jiva throughout the Vachanamrut. It is said to reside in our bodies in the same area as the heart. “Childhood, youth, old age, stoutness, thinness, birth and death are all aspects of the body; so they should never be thought of as belonging to the atma. On the other hand, being uncuttable, being unpierceable, not aging, being immortal, being the embodiment of gnan [wisdom], being the embodiment of bliss, and being characterized by eternal existence are all aspects of the atma; they should in no way be considered as belonging to the body.” The jiva is free and pure, but we believe that we are restrained by maya. Once we understand that we are not this body and worship Purna Purushottam Narayan, we realize that our jiva is free from the clutches of maya and is worthy of moksha. The very essence of the Brahma-Parabrahma spiritual journey is to believe one’s self to be the atma and not this body, to become atmarup, and to worship Purna Purshottam Narayan.
