Mbh 12.312.1a

"'"Yajnavalkya said, 'Listen to me, O foremost of men, as I tell thee what the duration of time is in respect to the Unmanifest (or the Supreme Purusha). Ten thousand Kalpas are said to constitute a single day of his. The duration of his night is equal. When his night expires, he awakes, O monarch, and first creates herbs and plants which constitute the sustenance of all embodied creatures. He then creates Brahman who springs from a golden egg. That Brahman is the form of all created things, as has been heard by us. Having dwelt for one whole year within that egg, the great ascetic Brahman, called also Prajapati (Lord of all creatures), came out of it and created the whole Earth, and the Heaven above. The Lord then, it is read in the Vedas, O king, placed the sky between Heaven and Earth separated from each other. Seven thousand and five hundred Kalpas measure the day of Brahman. Persons conversant with the science of Adhyatma say that his night also is of an equal duration. Brahmana, called Mahan, then creates Consciousness called Bhuta and endued with excellent essence.[1645] Before creating any physical bodies out of the ingredients called the Great elements, Mahan or Brahma, endued with penances, created four others called his sons. They are the sires of the original sires, O best of kings, as heard by us.[1646] It hath been also heard by us, O monarch, that the senses (of knowledge) along with the four inner faculties, have sprung from the (five Great elements called) Pitris, and that the entire universe of mobile and immobile Beings has been filled with those Great elements.[1647] The puissant Consciousness created the five Bhutas. These are Earth, Wind, Space, Water, and Light numbering the fifth. This Consciousness (who is a Great Being and) from whom springs the third creating, has five thousand Kalpas for his night, and his day is of equal duration. Sound, Touch, Form, Taste, and Scent,--these five are called Visesha.
