Sincerity is more important than procedure
“But 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. This is also confirmed in the Bhagavad-gita that He accepts foodstuffs from devotees because they are offered to Him in complete love and affection” (Srila Prabhupada Letter to Mandali Bhadra, 25th May, 1969).
