"The fluidic emanations of human beings could be compared to different types of gas. If we had laboratories with sufficiently sophisticated equipment, we could verify that some of these emanations are so polluted and impure that the effect they have in the psychic world is as toxic as poison gas. And we could also make the reverse observation: that the emanations of a spiritual being are extremely beneficial for all creatures. Such a being, by his presence, acts favourably on all those around him because he has conquered the human weaknesses, and even the spirits who have left earth go to him to feed themselves from his emanations. If the atmosphere of the earth has not yet become totally unbreathable it is because there are men and women who are disinterested, i.e. unbiased by personal interest, and full of love and who have devoted their life to peace and light."
