God (Paratma) in Hinduism is beyond the realm of time, as a result of which He is eternal. According to the Hindu philosophy, each living creature possesses a soul (inner core of consciousness) which is a part of this universal consciousness (that of God Himself). The life of a creature is thus a mortal attire which is changed with each birth and death event cycle that a soul passes through, whereas the soul itself being a part of the God exists for eternity.
What does the Hindu philosophy has to say about the Rakshasas (demons or anti-Gods)? Do they also have to pass through birth-death cycles? Do they possess souls and if so are their souls also a part of God? Can they achieve salvation, i.e. do their souls unify with the universal consciousness (paratma) ever?
