The Mahabharata/Book 1: Adi Parva…
“ And then the great Rishis, approaching the gods, spake unto them, 'Lo, in the middle of the night springeth a great heat striking terror into every heart, and destructive of the three worlds.' Then the gods, accompanied by the Rishis, wended to the Grandsire, and said unto him, 'O what is this great heat today that causeth such panic? Surya hath not yet risen, still the destruction (of the world) is obvious. O Lord, what will happen when he doth rise?" The Grandsire replied, 'Indeed, Surya is prepared to rise today for the destruction of the world. ”
