Take great care of the body as a trustee of God’s property. Do not pamper or spoil it, fill it with dirt or overload it.
XXXIII to XXXV translated from the Gujarati
And why no faith in prayer? Faith is either derived or revealed from within. You should derive it from the testimony without exception of all the teachers and seers of all climes, countries and times. A true prayer is not a mere lip expression. Selfless service is prayer. You must not say, ‘I have no faith in prayer.
