Does your repayment mean 'repaying his/her mother for raising him/her'?
You don't agree with the statement. I see. For your information, here is the entire original text:
Whenever society demands of a mother sacrifices to her child which go beyond reason, the mother, if she is not unusually saintly, will expect from her child compensations exceeding those she has a right to expect. The mother who is conventionally called self-sacrificing is, in a great majority of cases, exceptionally selfish towards her children, for, important as parenthood is as an element in life, it is not satisfying if it is treated as the whole of life, and the unsatisfied parent is likely to be an emotionally greedy parent.
