SB 9.15.9
tavat satyavati matra
sva-carum yacita sati
srestham matva tayayacchan
matre matur adat svayam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Meanwhile, because Satyavati’s mother thought that the oblation prepared for her daughter, Rcika’s wife, must be better, she asked her daughter for that oblation. Satyavati therefore gave her own oblation to her mother and ate her mother’s oblation herself.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
A husband naturally has some affection for his wife. Therefore Satyavati’s mother thought that the oblation prepared for Satyavati by the sage Rcika must have been better than her own oblation. In Rcika’s absence, the mother took the better oblation from Satyavati and ate it.
