The non-adherence to the notion of a supreme God or a prime mover is seen as a key distinction between Buddhism and other religious views. In Buddhism, the sole aim of the spiritual practice is the complete alleviation of distress ("dukkha") in "samsara", called "nirvana". The Buddha neither denies nor accepts a creator, denies endorsing any views on creation and states that questions on the origin of the world are worthless. Some teachers instruct students beginning Buddhist meditation that the notion of divinity is not incompatible with Buddhism, but dogmatic beliefs in a supreme personal creator are considered a hindrance to the attainment of "nirvana", the highest goal of Buddhist practice.
