Thus questioned, Kas'yapa replied:-- I heard that the serpent Taksak will bite the king Parîksit; therefore I am going in haste to the king Parîksit to cure him of the serpent's poison. I know the mantra (mystic verse) that can destroy the effect of poison. If his life-period is not exhausted, I will certainly give him back his life. Taksak then. Said:-- “O Brâhmana! I am that Taksak; I will bite him and take away his life. So you better desist. Will you be able to treat him whom I bite; certainly you will not.” Kas'yapa said:-- “O chief of snakes! When you will bite the king who has been cursed by the Brâhman, I will no doubt make him alive by the power of my mantra.” Taksak said:-- “O chief of Brâhmanas! If you have so thought that you will make the king alive after I bite him, then shew me your strength before hand. O sinless one! I will bite this Nyagrodha tree (the Indian fig-tree); just now make it alive.”
Kas'yapa said:-- “Certainly I will make this tree alive, that will be burnt away by the venom of your teeth.” Sûta said:-- “The snake Taksak then bit the tree, which was reduced to ashes; and asked Kas'yapa to bring back that tree to life.” Seeing the tree reduced to ashes by the fire of venom of the snake, he collected all the ashes and said:-- “O highly venomous serpent. See to-day the power of my mantra. Behold! While you are witnessing, I will enliven this tree. Thus the great mantra-knower Kas'yapa took water in his hand, and impregnating it with his mantra power, sprinkled the water on the ashes. Immediately, on the sprinkling of the mantra saturated water, the Nyagrodha tree got back its life as before. Taksak became greatly astonished to see the tree enlivened again and said to Kas'yapa:-- “O chief of Brâhmans! What is your object in taking so much pains? Speak out what you want and I will fulfil your desires.” Kas'yapa said:-- “O chief of serpents! Knowing the king cursed, I am going to do good to him by my knowledge and to get in return abundant wealth.” Hearing this, Taksak said:-- “I will give you the amount of wealth that you desire; take that and go back to your house, and let my desire be also fulfilled.”
