CC Ādi 5.71
jīvanti loma-vila-jā jagad-aṇḍa-nāthāḥ
viṣṇur mahān sa iha yasya kalā-viśeṣo
govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
This description of the Lord’s creative energy is from the Brahma-saṁhitā (5.48), which Lord Brahmā compiled after his personal realization. When Mahā-Viṣṇu exhales, the spiritual seeds of the universes emanate from Him in the form of molecular particles like those that are visible, three times the size of an atom, when sunlight is diffused through a small hole. In these days of atomic research it will be a worthwhile engagement for atomic scientists to learn from this statement how the entire creation develops from the spiritual atoms emanating from the body of the Lord.
