Gnosis is the Science of Mysticism!
The higher meaning of Gnosis is knowledge from experience, especially experience of divinity or that which is beyond the five senses. The word Gnosis does not refer to knowledge that we are told or believe in. Gnosis is conscious, experiential knowledge, not merely intellectual or conceptual knowledge, belief, or theory. Gnosis is Universal, it is synonymous with the Hebrew דעת “da’ath,” the Arabic ma’rifah, the Tibetan rigpa (knowing), and the Sanskrit “jna.” (Conscious Direct Experience)
Gnosis can also refer to the tradition that embodies the core wisdom or knowledge of all humanity. (Science, Art, Philosophy and Religion)
As for the knowledge we study here, it is profound, nearly incomprehensible, but ultimately only useful when made practical in your daily life. Live it, and the truth will be made starkly evident. Yet if this knowledge remains merely as concepts or beliefs, you will never, ever see what it really means.
