upādāna

Upādāna () is a Sanskrit and Pali word that means "fuel, material cause, substrate that is the source and means for keeping an active process energized". It is also an important Buddhist concept referring to "attachment, clinging, grasping". In Buddhism, it is considered to be the result of taṇhā (craving), and is part of duḥkha (dissatisfaction, suffering, pain).

==Buddhism== Upādāna is the Sanskrit and Pāli word for "clinging", "attachment" or "grasping", although the literal meaning is "fuel". Upādāna and taṇhā (Skt. tṛṣṇā) are seen as the two primary causes of dukkha ("suffering", unease, "standing unstable"). The cessation of clinging is nirvana, the coming to rest of the grasping mind.
