The phrase "has been given the heart to ask for the heart"
Friend? have you heard that phrase?
the expression is difficult to explain using words because the expression is a sentence in the practice of some people who are not good at thanking, and asking for excess for someone's gift.
The heart is a symbol of "love" while the heart is a symbol of "life", if possible simplified the language to be "already in love instead of asking for life" means
someone who willingly (because of love or pity or in the name of humanity) gives something to others, not saying thank you instead asking for additional gifts for his life.
