Abn Iblis ابن إبليس
Of course there is always more than one way something can be perceived and I will describe Satan and the Serpent from a Western LHP direction. Ravana from what I read is a mythical Hindu demon that acts as an antagonist to Man, Satan is not considered an antagonist but rather, as His name reveals, an Adversary.Satan / Ravan are the five vices which are responsible for the degradation and sorrow of mankind.
They are Lust , anger , greed , attachment and ego. All the evils originate from these 5 vices.
In most religions Satan is symbolized as a serpent , like the serpent which allures Adam and eve to eat the forbidden fruit .
In Hinduism a snake bites the gods and turns them black , a snake is also found around Shiv's neck probably representing that he tames those evils.
Satanists and Luciferians see the character of Satan as an archetype of pride, carnality, liberty, enlightenment, wisdom, and as a dark evolutionary force of entropy that permeates all of nature providing the drive for survival and propagation inherent in all living things.
As an archetypal structure, Satan is the reflection of how we perceive ourselves in relation to what we call the "others". Satan is a social and cultural phenomenon as old as the mind of humanity itself. There has always and will always, be essentially two worldviews consisting of oppositions and they are "Us & Them" or "Me" and "the rest of you" . . . etc.
The Serpent represents the the feminine spiritual principle, a divine force of creation that is able to carry out the idea of creation, awakening the power of creation and the sexual energy in man. Thus, man can reach the knowledge enabling him to become a god.
