PURPORT

The heat created by the flash of the Brahmastra resembles the fire in the sun globe which is exhibited at the time of annihilation of the cosmos. Radiation of atomic energy is very much insignificant in comparison with the heat produced by the Brahmastra. The atomic bomb explosion can utmost blow up one globe only but the heat produced by the Brahmstra can destroy the whole cosmic situation. The comparison is, therefore, made with the heat at the time of annihilation.
