Is it a sea? Is it a desert? Is it a dream?
Legend says that when Dattatreya walked on the earth, he stopped at the Black Hills and found a band of starving jackals. Being a god, he offered them his body to eat and as they ate, his body continually regenerated itself. Because of this, for the last four centuries, the priest at the temple has prepared a batch of prasad, cooked rice, that is fed to the jackals after the evening aarti.
Another, legend has it that there was once a holy man named Lakkh Guru residing at Kala Dungar and worshiping the Lord Dattatreya. He used to feed wild jackals. There came a day when he found he had no food, so cutting-off a part of his body he offered it to the jackals, saying, “Le ang!’ (Take body part). Over the centuries, this got corrupted to ‘Long’.
