“In traditional cultures (especially Asian), the right hand is utilized for positive, clean, upright actions, such as eating, making offerings, etc., while the left hand is used for hidden, unclean, or harmful actions. This tradition emerged from the ancient esoteric knowledge, unknown to the public, in which the followers of the light (divinity, purity) correspond to the "right-hand of God” while the adherents of impurity and desire fall to the left, into disgrace. These contrary paths are rooted in Sanskrit terms. Dakshinachara (Sanskrit दक्षिनाचार) literally means “upright in conduct” but is interpreted as “Right-Hand Path.” Vāmācāra (वामाचार) literally means “black magic,” or “ behaving badly or in the wrong way,” and is used to refer to “Left-Hand Path” or “Left-path” (Sanskrit: Vāmamārga वाममार्ग). These two paths are explained in Kabbalah as well.
In modern times, those who follow the left-hand path have worked hard to make their path seem respectable and equal to the right, by claiming the two need each other to exist. This argument is based on the lie that left-hand initiates pursue the darkness of the Uncreated Light, the Absolute (which is pure, divine), yet the reality is that their degeneration and harmful acts propel them into the darkness of the abyss, the hell realms, to be cleansed of their impurity. Followers of the left-hand path believe they can outwit Divinity.“
