Prasāda and food

In the temple, eat only prasāda

Do not bring food or drink into the temple. Eat only the prasāda that is given there.

The temple hall is a place of worship, and outside food and drink do not belong in it. Keep your snacks and bottles in the car or in the place provided, and take only what the temple offers as prasāda. Several temples state this in their visitor rules.
