Akshat

Akshat rice grain is offered to the Divine as a symbol of never ending abundance. Akshat in Sanskrit means 'that which cannot be destroyed'. Just as these rice grains, the spirit in me is indestructible, remembering this we offer the akshatas. Akshat/Rice Grains is one of the primary things without which the worship of the deity cannot be accomplished in a proper way. They are actually the symbols of prosperity and wealth.

The rice grain does not break ever. Scientists have said that matter and energy can never be created nor be destroyed. Similarly, also for the rice grain because it never gets destroyed or damaged. When we eat rice, it provides energy and nourishment to us and is absorbed by our body. And upon death, when our body is cremated and returns to the Earth element, the same rice grain after sometime grows from the Earth and becomes ready as food for consumption. When the body turns into ash, the ash becomes food for many fishes which in turn become the food for many other human beings again. So this happens again and again in Nature. When you bury the body under the Earth, the body dissolves away into the five elements.
They are Haldi with clours coated rice grains offered while doing puja, chanting mantras, performing yagna.
