What you can demand from Sai?
My dear children, my Guru's wealth is lying in the field in abundance. I am waiting to see when you realize the wealth and approach me for gifting you with the fortune. This fortune is not different from the wealth of liberation which is my Guru's treasure. You make claims for all other things except my Guru's treasure. You ask for petty worldly things. When will you ask for the recitation of name and meditation of form? When will you merge in God in absolute surrender? I cannot give you your choicest treasure unless you stop demanding material benefits and turn your face to the Lord.
