कालकर्मगुणोपेतो जगदादिरुपाविशत् ॥ ५० ॥
mahad-ādīni sapta vai
etāni — these; asaṁhatya — being unmixed; yadā — when; mahat-ādīni — the mahat-tattva, false ego and five gross elements; sapta — all together seven; vai — in fact; kāla — time; karma — work; guṇa — and the three modes of material nature; upetaḥ — accompanied by; jagat-ādiḥ — the origin of creation; upāviśat — entered.
When all these elements were unmixed, the Supreme Personality of Godhead, the origin of creation, along with time, work, and the qualities of the modes of material nature, entered into the universe with the total material energy in seven divisions.
After stating the generation of the causes, Kapiladeva speaks about the generation of the effects. At that time when the causes were unmixed, the Supreme Personality of Godhead, in His feature of Garbhodakaśāyī Viṣṇu, entered within each universe. Accompanying Him were all of the seven primary elements — the five material elements, the total energy (mahat-tattva) and the false ego. This entrance of the Supreme Personality of Godhead involves His entering even the atoms of the material world. This is confirmed in the Brahma-saṁhitā (5.35): aṇḍāntara-stha-paramāṇu-cayāntara-stham. He is not only within the universe, but within the atoms also. He is within the heart of every living entity. Garbhodakaśāyī Viṣṇu, the Supreme Personality of Godhead, entered into everything.
