Chanting Om Sri Sai Ram 108 times
"You are doing a lot of sadhana. You should do this with purity of heart. The greatest sadhana will be chanting the Name of the Lord and doing service to one’s fellow beings, who are the embodiments of the same Atma that is in you. Whatever you do, do it as an offering to the Divine."
