Bow to the Deity properly

Offer your obeisances when you see the Deity, and offer them with both hands, never one.

A bow is how the body says what the heart feels. The Nectar of Devotion warns against failing to bow before the Deity and against bowing with one hand only. Let your first act before the Lord be a full, unhurried bow.
