Mother: How old is Kṛṣṇa?
Prabhupāda: He is never old. That is material question. He is the oldest person. He is the origin of everything.
Mother: It is.
Prabhupāda: Yes. Therefore He is the oldest. That is stated in the Brahma... Advaitam acyutam anādim ananta-rūpam (Bs. 5.33), ananta-rūpam, ādyam, the origin, nava-yauvanam, but He is always young man. He is the oldest person. He is the original father, from whom we are all born, but He is always young. Nava-yauvanam. Nava, nava means newly youthful life. It is not that because Kṛṣṇa is the oldest person, therefore He has become very old. No. That is material conception. (whispering between mother and daughter) (pause)
