The meaning of Sarvasar, of the Sarvasar Upanishad, is the quintessential essence, the most foundational of all esoteric knowledge that has ever been discovered. In The Way beyond Any Way, Osho explains that understanding this one Upanishad will open doors to the ultimate truth. However, he also cautions that it is dangerous, like playing with fire, because an Upanishad cannot be completely understood without the reader becoming transformed. To encounter truth, even a little bit, is not a game; it is dangerous because the truth will change, demolish, destroy and renew a person. And this is what the Sarvasar Upanishad aims to do, to give new birth. Certainly, there is pain in birth, but without pain how can there be a new birth?
