Taṇhā is a Pāli word, related to the Vedic Sanskrit word tṛṣṇā and tarśa, which means "thirst, desire, wish". It is an important concept in Buddhism, referring to "thirst, desire, longing, greed", either physical or mental. It is typically translated as craving, and is of three types: kama-tanha (craving for sensual pleasures), bhava-tanha (craving for existence), and vibhava-tanha (craving for non-existence). Taṇhā appears in the Four Noble Truths, wherein taṇhā is the cause of dukkha (suffering, pain, unsatisfactoriness) and the cycle of repeated birth, becoming and death (Saṃsāra).
