Said Lord Sai Baba....
"You sit in Meditation for ten minutes after the evening Bhajan session; so far so good. But, let me ask, when you rise after the ten minutes and move about, do you see everyone in a clearer light as endowed with Divinity?
If not, Meditation is a waste of time. Do you love more, do you talk less, do you serve others more earnestly? These are the signs of success in Meditation. Your progress must be authenticated by your character and behavior.
Meditation must transmute your attitude towards beings and things, else it is a hoax. Even a boulder will, through the action of sun and rain, heat and cold, disintegrate into mud and become food for a tree. Even the hardest heart can be softened so that the Divine can sprout therein."
