Srimad-Bhagavatam: Canto 12 - Chapter 1 - Verse 12

Sanskrit:

तं तर्पयित्वा द्रविणैर्निवर्त्य विषहारिणम् ।द्विजरूपप्रतिच्छन्न: कामरूपोऽदशन्नृपम् ॥ १२ ॥

ITRANS:

taṁ tarpayitvā draviṇairnivartya viṣa-hāriṇamdvija-rūpa-praticchannaḥkāma-rūpo ’daśan nṛpam

Translation:

Takṣaka flattered Kaśyapa by presenting him with valuable offerings and thereby stopped the sage, who was expert in counteracting poison, from protecting Mahārāja Parīkṣit. Then the snake-bird, who could assume any form he wished, disguised himself as a brāhmaṇa, approached the King and bit him.

Purport:

Kaśyapa could counteract the poison of Takṣaka and demonstrated this power by bringing a palm tree back to life after Takṣaka had burned it to ashes by biting it with his fangs. According to the arrangement of destiny, Kaśyapa was diverted by Takṣaka, and the inevitable took place.
