Night of Brahma

ब्रह्मा - naɪt əv ˈbrəhmɑː

A period of one kalpa or a thousand mahayugas during which creation is unmanifested. [ref name=ebg]The Essence of the Bhagavad Gita, explained by Paramhansa Yogananda. Chapter 21, “Final Liberation.”[/ref]

Since the period of one mahayuga lasts for approximately 4.32 million years, the period of the night of Brahma is equivalent to 4.32 billion years. The period is the same as the period of one day of Brahma, or one kalpa. In Hindu cosmology, the kalpa is the length of one night of the universal creator Brahma.[ref]”The Hindu Theory of World Cycles: In the Light of Science,”[/ref]

During the night of Brahma, all of creation withdraws into an unmanifest state. Souls that were still manifest and not liberated during the day withdraw from outward manifestation but persist in “seed” form. Following the night, they appear in manifest form during the day of Brahma. [ref]Conversations with Yogananda, by Swami Kriyananda. Entry 91.[/ref]

Although one may misconceive of the night of Brahma as a period of cosmic dissolution, it is actually a time of quiescence. It may be conceived of as a wintertime during which the seeds of creation lie dormant; although unmanifest, the forms of consciousness are particles of universal consciousness. The night of Brahma differs from the Absolute Unmanifest, which remains eternally untouched by the cycles of creation. [backref name=ebg]
