In Digambar Jain practice, rice is offered in ashtadravya puja as Akshat.

How to offer rice

1. Use clean, uncooked rice.
2. The rice should be white, whole, and unbroken.
3. It is usually placed in the puja thali as Akshat.
4. While offering, it is done with devotion, purity, and reverence before the Jina image.
5. In Digambar tradition, rice is generally used to symbolize wholeness, purity, and auspiciousness.

Important point

• The rice should not be cooked.
• It should be offered as part of bhaav-puja, with the inner भावना of devotion.
• In many Digambar rituals, akshat is offered after other dravyas in the proper puja sequence.

Simple meaning

• shuddhata (purity)
• samarpan (devotion)
• purnata (completeness)
