Gayatri

The venerable Bhisma, while extolling the greatness of the Gayatri from his bed of arrows declares; “Where the Gayatri is chanted, untimely deaths involving the performance of obsequies for children by their elders will not occur”. Thus it is a prayer for universal welfare which the initiated must perform as a sacred trust enjoined upon him.
