All the matter of the world that surrounds us, the food that we eat, the water that we drink, the air that we breathe, the stones that our houses are built of, our own bodies — everything is permeated by all the matters that exist in the universe. There is no need to study or investigate the sun in order to discover the matter of the solar world; this matter exists in ourselves and is the result of the division of our atoms. In the same way we have in us the matter of all other worlds. Man is, in the full sense of the term, a “miniature universe”; in him are all the matters of which the universe consists; the same forces, the same laws that govern the life of the universe, operate in him; therefore in studying man we can study the whole world, just as in studying the world we can study man.

P. D. Ouspensky (1878 – 1947)
