Bhāgavatam is the Answer
551
reference pertains to the sixteen elementary manifestations of earth, water, etc., with material ego composed of material intelligence and mind, and the subsequent creation is a result of the reactions of the above-mentioned sixteen energies of the first  puruṣa , the Mahā-Viṣṇu incarnation of Govinda, as is later on explained by Brahmā in his treatise the  Brahma-saṁhitā  as follows:
yaḥ kāraṇārṇava-jale bhajati sma yoga- nidrām ananta-jagadaṇḍa-saromakūpaḥ ādhāra-śaktim avalambya parāṁ sva-mūrtiṁ govindam ādi-puruṣaṁ tamahaṁ bhajāmi  (B.s. 5.47)
The first  puruṣa  incarnation of Govinda, Lord Kṛṣṇa, known as the Mahā-Viṣṇu, goes into a  yoga-nidrā  mystic sleep, and the innumerable universes are situated in potency in each and every hair hole of His transcendental body.
As is mentioned in the previous verse,  śrutena  (or with reference to the Vedic conclusions), the creation is made possible from the Supreme Personality of Godhead directly by manifestation of His particular energies. Without such a Vedic reference, the creation appears to be a product of material nature, and this conclusion comes from a poor fund of knowledge. From Vedic reference it is concluded that the origin of all energies (namely internal, external, and marginal) is the Supreme Personality of Godhead. And as has been explained hereinbefore, the illusory conclusion is that creation is made by the inert material nature. The Vedic conclusion is transcendental light, whereas the non-Vedic conclusion is material darkness. The internal potency of the Supreme Lord is identical with the Supreme Lord, and the external potency is enlivened in contact with the internal potency. The parts and parcels of the internal potency which react in contact with the external potency are called the marginal potency, or the living entities.
Thus the original creation is directly from the Supreme Personality of Godhead, or  Param Brahman , and the secondary creation, as reactionary resultant of the original ingredients, is made by Brahmā, and the activities of the whole universe are thus started.
