self-knowledge/knowledge of self

cosmological/higher-self-knowledge or knowledge of self derived by deep introspection, uninhibited creative self-expression or spiritual work and study commonly employing the practice of meditation, the use of marijuana/ganja as holy sacrament or the shamanic use of psychedelic drugs to attain deeper inter-dimensional spiritual insight into the nature and character of one's esoteric essence and the latent capabilities thereof

The concept of self-knowledge or knowledge of self has been propagated by numerous sources over the ages: we have the Egyptian-schooled Greek's aphorism "know thyself", the notion of knowledge of self spoken of in Islamic teachings based off the Koran passage, "He who knows himself knows God," and then there is the popular use of the term "self-knowledge" that was reportedly introduced into hip-hop culture by the Five Percenters (a splinter faction of the Nation of Islam founded by Clarence 13X, a former student of Malcolm X) that became known as the fifth element of hip-hop among the other four (1. graffiti, 2. MCing, 3. b-boying/girling, 4.DJing).
Blessed with the wisdom of self-knowledge/knowledge of self ol' boy be spitting some conscious shit.

The Knowledge is the in-depth study of London street routes and places of interest that taxicab-drivers must complete to obtain a licence to operate a black cab. It was instigated in 1851, and has changed little since.

It is the world's most demanding training course for taxicab-drivers; and applicants will usually need at least 12 'Appearances' (attempts at the final test), after preparation averaging 34 months, to pass the examination.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
