Kali, a demon who holds friendly converse with the gods in the “Story of Nala”, is attended by Dwápara, a flesh-eater like the Pisachas. The Panis are aerial demons, who are hated by bluff, honest Indra, because they are the inspirers of foolish actions, slander, and unbelief, and the imps who encourage men to neglect homage to deities. The black Dasyus are repulsive of aspect and jealous-hearted; they are the stealers of the cloud cows who are held captive for Vritra in the cave of the demon Vala. The Darbas, “the tearers”, are a variety of Pisachas. Reference is made in _Mahabharata_ to “ugly Vartikas of dreadful sight, having one wing, one eye, and one leg”; when they “vomit blood, facing the sun”, a dreadful happening is known to be at hand, because they are fiends of evil omen. Among the supernatural beings who are sometimes the enemies, but in most cases the friends of mankind, are the Yakshas, the Gandharvas, and the Apsaras (Apsarasas). The Yakshas are occasionally referred to as the Punyajanas, “the good people”; they may be of human stature, with big benevolent eyes, or powerful giants who can fight as fiercely as Rakshasas. They are guardians of hidden treasure, like the dwarfs and giants of Teutonic legend, being associated with Kuvera, god of wealth, whose abode is situated among the Himalayan mountains. In Kuvera's domain are found “multitudes of spirits” who do not visit the world of men as a rule, but remain near the treasure for purposes of defence; “some are of dwarfish stature, some of fierce visage, some hunchbacked, some of blood-red eyes, some of frightful yells; some are feeding upon fat and flesh, and some are terrible to behold; and all are armed with various weapons, and endued with the speed of the wind”.[123] [123] _Mahabharata_, Roy's trans.
