To me religion consists of three layers; the first layer is of science. Just as your body consists of material, atomic constituents, so religion consists first, the most peripheral part, of science. I am not against science -- science is an absolute need -- but it is only a peripheral phenomenon, the most superficial, the first concentric circle around your center.
Then comes the second concentric circle, which is deeper than science; that is of art, aesthetics. And then the third; that is meditation. And if you have entered these three concentric circles, slowly slowly you will attain to the fourth.
The fourth in the East is called TURIYA; we have not given it any name, we have simply given it a number, "the fourth." Nothing can be said about it, that's why no name has been given to it. It is even beyond mystery. Meditation will take you into the mysterious, but there is still something more than that; that is inexpressible. Nothing can be said about it, nothing has ever been said about it, nothing will ever be said about it, but it has been experienced.
Only at that ultimate peak of experience, in that ultimate ecstasy, will you know what it is to be.
