One of Naran Sir students had lost his mother at an age fairly young according to him. He was always thinking that she should not have died that young, that it was not fair etc., He had not been able to accept his mother's death or let it go.
Naran Sir gave him Kalam Namamyaham CD mantras and he listened to it. After a month or so, he came and visited Naran Sir.
He said he felt acceptance now and had let it go. He wondered why the mantras helped in this.
