Enlightenment refers to the “full comprehension of a situation”. It 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.
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,[web 1] and has also gained insight into the way that leads to nirvana, the liberation of oneself from this imprisonment.
Prajna is a Mahayana term. It refers to insight into our true nature, which according to Madhyamaka is empty of a personal essence in the stream of experience. But it also refers to the Tathāgata-garbha or Buddha-nature, the essential basic-consciousness beyond the stream of experience.
In Zen, kensho means “seeing into one’s true nature”. Satori is often used interchangeably with kensho but refers to the experience of kensho.
Buddhahood is the attainment of full awakening and becoming a Buddha. According to the Tibetan Thubten Yeshe, enlightenment
[means] full awakening; Buddhahood. The ultimate goal of Buddhist practice, attained when all limitations have been removed from the mind and one’s positive potential has been completely and perfectly realized. It is a state characterized by infinite compassion, wisdom, and skill.
Well, this is very interesting. She gives multiple religious definitions. Even though structured religion is used to define Spiritual Enlightenment, she does a great job at keep the explanations short and easy to read. I can get into it! Just because it’s structured religion, it doesn’t mean there is some insight available.
Huw E-Maillard, “Eclectic collector of thoughts on existence and creation and Bible Student”
By means of meditation, sensory deprivation, fasting or entheogens we reach a different realm. A realm where our egos don’t take up any space. In that realm, we realize that there’s no material reality. That all there is thought expressing itself as matter. That all matter is mind. That together we’re all one mind. That everyone and everything is one thing only. That boundaries don’t exist for real. That separateness’s just our ego’s creation. That our ego is what gets between us and the One. The whole. The creator, nature, universe, whatever.
They’re all but different words to describe the same thing: Infinite love with a guiding intelligence.
What we are talking about is one word that is the object of all Religions and all Spirituality: TRANSCENDENCE. A realm so close to our mundane reality and yet so difficult for most to perceive.
