Question: So what is the form and what is the definition of soul, and how to know whether there is soul...?
Prabhupāda: That is... that is... that is described. We are describing na jāyate na mriyate. Soul is never born, soul never dies. Soul is eternal. Nityaḥ śāśvato 'yaṁ na hanyate hanyamāne śarīre (BG 2.20). Even after the destruction of this body, the soul is not destroyed. These, these are the education.
