As long as you live inside the house of maya, as long as there exists the cloud of maya, you do not see the effect of the Sun of Knowledge. Come outside the house of maya, give up 'woman and gold', and then the Sun of Knowledge will destroy ignorance. A lens cannot burn paper inside the house. If you stand outside, then the rays of the sun fall on the lens and the paper burns. Again, the lens cannot burn the paper if there is a cloud. The paper burns when the cloud disappears.
