There is a mountain between लोक and अलोक . This is called लोकालोकपर्वत and the land beside it is called लोकालोक . The mountain is as long as the distance between मानसोत्तर and महामेरु . This place is golden in colour and as smooth as glass. Not a single being lives there. God has created this as a boundary to the three worlds. All the planets like the Sun get light from the brilliance of this mountain. ब्रह्मा has posted four diggajas named वृषभ , पुष्पचूड , वामन and अपराजित in the four corners of this mountain. (8th Skandha, Devī Bhāgavata) .
