mention in Mahabharata is Sthunakarna. He dwelt in a forest close to the Panchala Kingdom. He converted Shikhandini, the daughter of Panchala king Drupada into a male by exchanging his male sexuality with her. Here the Yaksha is addressed as a Guhyaka, the one who dwells in caves or in hidden places. There was a dense and solitary forest that was the haunt of a very formidable Yaksha called Sthunakarna. From fear of that Yaksha men never went into that forest. And within it stood a mansion with high walls and a gateway, plastered over with powdered earth, and rich with smoke bearing the fragrance of fried paddy. Entering that mansion, Sikhandini, the daughter of Drupada, began to reduce herself by foregoing all food for many days. Thereupon, the Yaksha named Sthuna, who was endowed with kindness, showed himself unto her (5,194). Mystification of Yakshas At 3:310 of Mahabharata is a conversation of a Yaksha and Pandava king Yudhishthira. Here Yaksha is described as a crane, sitting by a pond. Manibhadras, and Vaisravana (Kubera), the king of the Yaksha were worshipped by travellers who travel through lonely territories, for protection against dangers. Manibhadra is one of the warrior in the Yaksha army of Kubera. Gandharvas were also part of his army (3:65). At 3:229 this is more clear: The man who beholds Dewa (people) while sleeping, or in a wakeful state soon turns mad, and the spirit under whose influence these hallucinations take place is called the Deva spirit. When a person beholds his dead ancestors while he is seated at ease, or lying in his bed, he soon loses his reason, and the spirit which causes this illusion of sensible perception, is called the ancestral spirit. The man who shows disrespect to the Siddhas and who is cursed by them in return, soon runs mad and the evil influence by which this is brought about, is called the Siddha spirit. And the spirit by whose influence a man smells sweet odour, and becomes cognisant of various tastes (when there are no odoriferous or tasteful substances about him) and soon becomes tormented, is called the Rakshasa spirit. And the spirit by whose action celestial musicians (Gandharvas) blend their existence into the constitution of a human being, and make him run mad in no time, is called the Gandharva spirit. And that evil spirit by whose influence men are always tormented
