Curtain Of Ignorance
Removing ignorance is called avaran.
Avaran is a layer on our consciousness and means blindness, darkness. An obstacle which is like a curtain and it needs to be removed. How to remove? The only way is knowledge. Until it is not removed our development will not be. We will learn but as long as there is no gyana, we are still greedy. Only if we have gyana, the right knowledge, we can serve God's creation.
