SB 4.7.8
vidhaya kartsnyena ca tad
yad aha bhagavan bhavah
sandadhuh kasya kayena
savaniya-pasoh sirah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
After everything was executed exactly as directed by Lord Siva, Daksa’s body was joined to the head of the animal meant to be killed in the sacrifice.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
This time, all the demigods and great sages were very careful not to irritate Lord Siva. Therefore whatever he asked was done. It is specifically said here that Daksa’s body was joined to the head of an animal (a goat).
