सोम , personified as इन्दु , is exalted as a powerful force that purifies and sustains. Hailed as the giver of blessings, food, and joy, सोम purifies in water and shines like the sun. It is revered as vital to the holy rites and is entreated to provide abundance, embodying cosmic endurance and the soul of sacrifices [rv-9-2-1 ] rv • Book 9 .
