TRANSLATION
“Lord Kṛṣṇa exhibits His pastimes of childhood, boyhood and pre-youth. When He reaches pre-youth, He continues to exist eternally to perform His rāsa dance and other pastimes.
PURPORT
The comparison made here is very interesting. Kṛṣṇa does not grow like an ordinary human being, even though He exhibits His pastimes of childhood, boyhood and pre-youth. When He reaches the age of pre-youth,  kaiśora , He does not grow any older. He simply remains in His  kaiśora  age. He is therefore described in  Brahma-saṁhitā  (5.33) as  nava-yauvana .
advaitam acyutam anādim ananta-rūpam ādyam purāṇa-puruṣam nava-yauvanam ca vedeṣu durlabham adurlabham ātma-bhaktau govindam ādi-puruṣam tam aham bhajāmi
This  nava-yauvana , or pre-youth, is the eternal transcendental form of Kṛṣṇa. Kṛṣṇa never grows older than  nava-yauvana .
