On this day, Sachi, the consort of Indra, tied a holy thread or amulet around the wrist of Indra, when he was defeated by the demons. Then Indra, the king of gods, gained victory over the demons by the power of this protection (Raksha means “protection”) and recovered the lost city of Amaravati.
Brahmins and Purohits similarly tie amulets round the wrists of their patrons and receive gifts.A Mantra is recited when the Rakhi or the silken thread is tied. The silken thread is charged with the power of the Mantra, which is as follows:
“I am tying on your hand this Raksha, with which the most powerful and generous King Bali himself was bound; O Raksha, don’t go away; don’t go away.” The power of this Mantra protects the wearer from evil influences.
