Then the Gâyatrî Devî told Gautama with amazement:-- “O Gautama! The venom of the snake does not become less if you feed the serpents with milk; so never mind all these things; the Karmas take their peculiar turns; it is hard to say when will happen what things. Now be peaceful. Do not be sorry.” Hearing these words of the Devî, Gautama bowed down to Her and went thence to his own Âs’rama. Here, on the other hand, the Brâhmanas forgot everything due to the curse of Gautama, of the Vedas and the Gâyatrî Mantra. They then began to look at this event with wonder as unique and extraordinary. All united they afterwards repented and going before Gautama, fell prostrate at his feet. But they could not speak any word out of shame. Only they said frequently:-- “Be pleased, be pleased with us.” When all the assembly of the Brâhmanas prayed to him for favour and grace, the Muni Gautama took pity on them and replied. My word will never turn out false. You will have to remain in Kumbhîpâka hell upto the time when S’rî Krisna will take his incarnation. Then you will be born in the earth in the Kâlî age and whatever I have uttered will exactly come unto you. And if you are in earnest to avert my curse then go and worship the Lotus Feet of S’rî Gâyatrî Devî. The is no other remedy.
