The difference between those whose nervous centers respond and those whose nervous centers do not respond is that of rock and plant. The rock does not respond to sympathy, but the plant does. And so the ones whose intuitive centers are awakened to some extent begin to feel intuitive, and then inspiration and revelation follow. But one should bear in mind that these things are not to be talked about. Those who know least talk most; and then if those who are not yet ready to know these secrets get hold of some theory or other of this kind, they speak about it to everybody. And then they write a book about their own wrong conceptions. They have never had the patience, perseverance, and right guidance to help them, and often they go astray; and many of them have damaged their health and got out of balance trying to awaken centers. They make light of something which is most serious, most sacred, and which leads to spiritual attainment. Others make fun of it, those of the wrong quality who cannot perceive sympathy as a plant perceives it. They do not see the possibilities in themselves and mock at those who do perceive; and in this way a science, which is the highest of all sciences, has been abused and laughed at.
