Left and right thinking derive from religious context dating back even before Judaism. Left represents living with free will as professed in esoteric ideologies while right represents ideologies professing living under ethical codes. Even within the occult ideologies there is left-hand path and right-hand path. Although, in that context left-hand path represents the worst of all evil.



Such condescension and misrepresentation of my message.
Left and right handed in context of spirituality dates to tantric origins. Vāmācāra and Dakṣiṇācāra are Sanskrit defining those very terms. I happen to know this based on my years of studies. While it was later reused by occultists in the late 1800s it appears the same is true during the late 1700s as well.
When researching maybe learn to invest your time in research rather than performing a 60 second internet search only to wind up on Wikipedia. Better to actually educate yourself, and others, on scholarly works rather than take the easy path of a charlatan to appear intelligent on a forum.
