Enlightenment is the "full comprehension of a situation". The term is commonly used to denote the Age of Enlightenment, but is also used in Western cultures in a religious context. It translates several Buddhist terms and concepts, most notably bodhi,kensho and satori. Related terms from Asian religions are moksha (liberation) in Hinduism, Kevala Jnana in Jainism, and ushta in Zoroastrianism.
In Christianity, the word "enlightenment" is rarely used, except to refer to the Age of Enlightenment and its influence on Christianity. Roughly equivalent terms in Christianity may be illumination, kenosis, metanoia, revelation, salvation and conversion.
Perennialists and Universalists view enlightenment and mysticism as equivalent terms for religious or spiritual insight.
The English term "enlightenment" has commonly been used to translate several Sanskrit, Pali, Chinese and Japanese terms and concepts, especially bodhi, prajna, kensho, satori and buddhahood.
Bodhi is a Theravada term. It literally means "awakening" and "understanding". Someone who is awakened has gained insight into the workings of the mind which keeps us imprisoned in craving, suffering and rebirth, and has also gained insight into the way that leads to nirvana, the liberation of oneself from this imprisonment.
