Mara (Sanskrit: मार, Māra; Chinese: 天魔; pinyin: Tiānmó; Tibetan Wylie: bdud; Khmer: មារ; Burmese: မာရ်နတ်; Thai: มาร; Sinhalese: මාරයා), in Buddhism, is the demon that tempted Gautama Buddha by trying to seduce him with the vision of beautiful women who, in various legends, are often said to be Mara's daughters. In Buddhist cosmology, Mara is associated with death, rebirth, and desire.Nyanaponika Thera has described Mara as "the personification of the forces antagonistic to enlightenment."
The word "Māra" comes from the Proto-Indo-European root *mer meaning to die. The Sanskrit form of the verbal root is √mṛ. It takes a present indicative form mṛyate and a causative form mārayati (with strengthening of the root vowel from ṛ to ār). Māra is a verbal noun from the causative root and means 'causing death' or 'killing'. It is related to other words for death from the same root, such as: maraṇa and mṛtyu. The latter is a name for death personified and is sometimes identified with Yama.
In traditional Buddhism four metaphorical forms of "māra" are given:
Early Buddhism acknowledged both a literal and psychological interpretation of Mara. Specially Mara is described both as an entity having an existence in Kāma-world, just as are shown existing around the Buddha, and also is described in paṭiccasamuppāda as, primarily, the guardian of passion and the catalyst for lust, hesitation and fear that obstructs meditation among Buddhists.
