The Full Form of LHP is Left-Hand Path.

The left-hand path is considered to be about the elevation and centrality of the self as well as the rejection of religious authority and societal taboos.

The left-hand path focuses on the strength and will of the practitioner. It downplays the need for intercession by any high power although some may believe that a higher power exists.

Satanism (both LaVeyan and Theistic) and Luciferianism are considered left-hand paths. Followers of Thelema disagree whether it is a left- or right-hand path.

What Is the Right-Hand Path?

The right-hand path, in the words of left-hand path follower Vexen Crabtree, “concentrate[s] on the symbols of goodness, of the sun, of herd mentality and submission to god(s) and religious authority.”​

To put it a little more diplomatic, the right-hand path can be thought of as one of dogma, ritual, and a belief in the community and formal structure as well as a higher power. Though each of those can also be found in left-hand path religions, there is less focus on indulging the self in the right-hand path. 

The vast majority of religions are considered part of the right-hand path, from Christianity to Wicca.
