What is the importance of offering Akshata

What is the importance of offering Akshata (unbroken rice grains) to the ritualistic worshipping of God Shiva ?
It is appropriate to make use of Akshata during the worship of the Pindi because they indicate detachment or spiritual practice
without expectation. The fundamental frequencies of the higher Deities related to the Nirgun (unmanifest) are attracted towards the Akshata. God Shiva is a higher Deity with maximum
relation to the Nirgun state; by using Akshata in worship of the pindi, one gets maximum benefit of the Shiva principle
