I am listening to one of your lecture and an inquiry is made about chanting rounds or the Holy Name etc. for others.

In the Gita mahatmya there is one section where a bull is dying and all the people come and promise to give some of their accrued punya to the bull including a prostitute – she did it because she didn't want be the one who didn't because she thought she had no punya to give. But because the blessing from the prostitute alone the bull was born as a high brahmana and traced her out to find out what was her punya etc. She confessed that she was a prostitute and actually had no punya. But after some thought it was revealed that she had some parrots who used to belong to someone who chanted a specific chapter of the Gita daily and she used to listen to that and for this reason she had punya etc. So it seems that one can gift one's own punya to others. How would you explain this?
