PratītyasamutpādaPratītyasamutpāda (Sanskrit: प्रतीत्यसमुत्पाद, Pāli: paṭiccasamuppāda), commonly translated as dependent origination, or dependent arising, is a key doctrine in Buddhism shared by all schools of Buddhism. It states that all dharmas (phenomena) arise in dependence upon other dharmas: "if this exists, that exists; if this ceases to exist, that also ceases to exist". The basic principle is that all things (dharmas, phenomena, principles) arise in dependence upon other things.
BhavacakraThe bhavacakra (Sanskrit: भवचक्र; Pāli: bhavacakka; Tibetan: སྲིད་པའི་འཁོར་ལོ, Wylie: srid pa'i 'khor lo) is a symbolic representation of saṃsāra (or cyclic existence). It is found on the outside walls of Tibetan Buddhist temples and monasteries in the Indo-Tibetan region, to help non Buddhists understand Buddhist teachings. It is used in Indian Buddhism and Tibetan Buddhism. Bhavachakra, "wheel of life," consists of the words bhava and cakra. bhava (भव) means "being, worldly existence, becoming, birth, being, production, origin".
