Do Sikhs Believe in the Devil or Demons?

The Sikh scripture, Guru Granth Sahib, makes references to demons mentioned in Vedic legends primarily for illustrative purposes. There is no belief system in Sikhism which focuses on demons or devils. Sikh teachings center on ego and its effect on the soul. Indulging in unbridled egoism may render a soul subject to demonic influences and the realms of darkness which abide within one’s own consciousness.

Actually – in the Bible it does mention angels and the devil. But Sikhs don’t believe in that because one himself is responsible for his own actions. But we all know Christianity does believe in angels and the devil.
