I'd like to know the "atom". According to Śrī brahma-saṁhitā 5.35,
Kṛṣṇa is present in His fullness in every one of the atoms that are scattered throughout the universe. I can't figure out atom. It seems like capsule which made from mahat-tattva. Srila Prabhupada wrote that the atom is the minute subtle form of eternal time. That confuses me even more.
So, what constitutes atom?
