SB 6.10.7
sri-rsir uvaca
dharmam vah srotu-kamena
yuyam me pratyudahrtah
esa vah priyam atmanam
tyajantam santyajamy aham
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The great sage Dadhici said: Just to hear from you about religious principles, I refused to offer my body at your request. Now, although my body is extremely dear to me, I must give it up for your better purposes since I know that it will leave me today or tomorrow.
