The age of Brahmā is calculated in terms of *divya* years, which are distinct from the solar years of human beings. The *divya* years are calculated in *Bhagavad-gītā* [[bg/8/17|(Bg. 8.17)]]: *sahasra-yuga-paryantam ahar yad brahmaṇo viduḥ.* Brahmā's one day is equal to one thousand times the aggregate of the four *yugas* (calculated to be 4,300,000 years). On that basis, Brahmā meditated for one hundred years before he could understand the supreme cause of all causes, and then he wrote the *Brahma-saṁhitā,* which is approved and recognized by Lord Caitanya and in which he sings, *govindam ādi-puruṣaṁ tam ahaṁ bhajāmi .* One has to wait for the mercy of the Lord before one can either render service unto Him or know Him as He is.
