A period of one kalpa or a thousand mahayugas during which creation is manifested. (1)
Since one mahayuga lasts for approximately 4.32 million solar years, the day of Brahma is equivalent to 4.32 billion solar years. The kalpa comprises four ages or yugas, namely Satya Yuga, Treta Yuga, Dwapara Yuga, and Kali Yuga. In Hindu cosmology, one kalpa is considered to be the length of one day of the creator Brahma. (2)
At the dawn of Brahma’s Day, all of creation emerges from the state of unmanifestation. (1) The period of Brahma’s Day encompasses the complete cycle of cosmic manifestation. In other terms, the cosmic vibration AUM, which constitutes all of creation, passes through the stages of “A” or creation, “U” or preservation, and “M” or dissolution. (3)
During the day, souls born into the cycle of reincarnation may realize themselves before the fall of Brahma’s Night. (1) However, if the souls fail to recognize themselves as spirit, during the period of Brahma’s Day following the period of night, the souls must reenter the realm of creation. (4)
