Lecture V
What is pure Brahman? When we breathe in the air and breathe it out again the materialistic person believes he is only inhaling oxygen. But that is a delusion; with every breath we inhale and exhale spirit. The spirit that lives in the air we breathe penetrates into us and goes out from us again. And when an old clairvoyant saw that, he did not, like the materialist, believe that he was breathing in oxygen. That is a materialistic prejudice. The clairvoyant of ancient times was aware that the etheric element of the spirit, Brahman, from whom all life comes, was being inhaled. In the same way that today we believe that life comes from the oxygen in the air, so did ancient man know that life comes from Brahman; and in that he takes up Brahman, he lives. The purest Brahman is the source of our life.
