Serving the Deity

Do not neglect the rules of worship

Serve the Deity with care and in order. Do not let the regular rules of worship slip through carelessness.

Regularity is part of love. The Nectar of Devotion lists neglecting the strict rules of worship among the offenses to avoid. If you serve at a home altar, keep a simple routine you can follow every day instead of a long one you cannot.
