sańkhyānaḿ paramāṇūnāḿ
kālena kriyate mayā
na tathā me vibhūtīnāḿ
sṛjato 'ṇḍāni koṭiśaḥ
sankhyanam -- counting; parama-anunam -- of the atoms; kalena -- after some time; kriyate -- is done; maya -- by Me; na -- not; tatha -- in the same way; me -- of Me; vibhutinam -- of the opulences; srijatah -- who am creating; andani -- universes; kotisah -- by the innumerable millions.
The Lord here explains that Uddhava should not expect a complete catalog of the Lord's opulences, since even the Lord Himself finds no limit to such opulences. According to Srila Jiva Gosvami, kalena indicates that the Supreme Personality of Godhead is within every atom and can therefore easily calculate the total number of atoms. However, although the Lord is certainly omniscient, even He Himself cannot supply a finite number for His opulences, because they are infinite.
