Prabhupāda: When this shirt is not workable you change it. Similarly, this body is just like shirt and coat, when it is no longer workable, we have to change.
Bob: What is the "we" that has to change? What is constant between one life to the next?
Prabhupāda: That is soul. That is soul, "I", what you are speaking, "you", what I am speaking, identification, ātmā, or soul.
Bob: My soul is different than your soul?
Prabhupāda: Yes. You are individual soul, I am individual soul.
