The Yakshas (Sanskrit: यक्ष, IAST: Yakṣa, Pali: Yakkha) are a broad class of nature spirits, usually benevolent, but sometimes mischievous or capricious, connected with water, fertility, trees, the forest, treasure and wilderness.[4][5] They appear in Hindu, Jain and Buddhist texts, as well as ancient and medieval era temples of South Asia and Southeast Asia as guardian deities.[5][6] The feminine form of the word is IAST: Yakṣī[7] or Yakshini (Sanskrit: यक्षिणी, IAST: Yakṣiṇī; Pali: Yakkhini).[8]
In Hindu, Jain and Buddhist texts, the yakṣas have a dual personality. On the one hand, a yakṣa may be an inoffensive nature-fairy, associated with woods and mountains; but there is also a darker version of the yakṣa, which is a kind of (bhuta) that haunts the wilderness and waylays and devours travellers, similar to the rakṣasas.
