Next, this Self is like a dam. It supports the worlds and protects them from getting mixed up. Day and night cannot cross over this dam, nor can old age, death, bereavement, good actions, and bad actions. All sins turn away from it, for this Brahmaloka is free from evil.
Therefore, by crossing this dam, if you are blind, you do not feel you are blind. Similarly, if you are hurt, you do not feel you are hurt, and if you are mentally upset, you no longer feel the sorrow. This is why if you cross this dam, even night will be like day, for this world of Brahman is always full of light.
Those who attain this Brahmaloka through brahmacarya become the masters of Brahmaloka. They can visit all worlds as they like.
