If a person meets a true and genuine saint, he transforms himself to a loving person and tears of joy will roll down his face for such a saint.
When Bapa was in his tender years, a saint visited him and blessed him that when he grows up, He (Bapa) will become a great saint and the holy man's words cannot go wrong and exactly the same happened as destined in Bapa's life.
All this has been explained in the holy script of our ancient Ved Purana.
