By Gautam Saha
One day of Brahma equals 4 billion, 320 million years. Since Brahma’s night is of the same length, and he lives for 100 Brahma years, in earth time, his age is 310 trillion years. According to Vedic estimates, Brahma has lived about half of his life so far, and a similar period will elapse before he dies, Brahma also being under the control of kaal (time) and mahamaya (the Lord’s external creative potency). Both are insurmountable potencies of the Supreme Lord Visnu. Brahma’s present age is about 155 trillion earth years.
