In everything we do devotion and sincerity are the real things. There is a word in Sanskrit; bhava grahi janardana. This means the Lord accepts service in devotional emotion. If we are sincere in offering something to the Lord in devotional love, He will accept it. The procedure may not be very right, but the desire being sincere, He accepts our offering.
Letter to Mandali Bhadra, 25 May, 1969
