"Mother Yashoda’s love is unmatched in purity and is unlike any other that even the infinite Lord who pervades the entire creation is bound by her love."
“Because mother loves the most…in this material world, there is no comparison of mother's love. Without any exchange. Even in this material world. Mother loves the child without any expectation of return generally…that is called unalloyed love. Anyabhilasita-sunyam, free from all material gain.”- Srila Prabhupada Srimad-Bhagavatam1.8.31 lectu
