If we are brahman, then why even be human beings? Why even be tent beings? Why at all this game of life? The straight answer to your question is, it does happen. That's what is going on. Massive change has to be direxte and be careful of making massive changes externally. It generally doesn't work. When things go our way, e find the moment you withdraw from life and you centre yourself, things will begin to go your way. You will notice external world begins to fall in place. Things go nicely. And then that is the test, will you stick to your spiritual life, or enjoy the new found peace and niceness all around?
Swami Sarvapriyananda teaches the Katha Upanishad, which is one of the most popular Upanishads. The scripture concerns the story of a young man who goes to the house of death to find out what happens after death. The reply describes the nature of reality and the meaning of life.
