Occultism is a knowledge of invisible forces, their different vibrations, their interrelations, the combinations which can be made by bringing them together and the power one can exercise over them. It is absolutely scientific; and it ought to be learnt like a science; one cannot practise occultism as something emotional or something vague and imprecise. You must work at it as you would do at chemistry, and learn all the rules or find them if there is anybody to teach you. But it is at some risk to yourself that you can find them. There are combinations here as explosive as certain chemical combinations.
You must not touch the occult science if you have the least fear in you, on the other hand, the most frightful dreams leave you absolutely calm, and even at times amused and you know how to get out of the difficulty in every circumstance, then that means that you have the ability and can do it. Some people are very brave warriors in their dreams. When they meet enemies, they know how to fight; they know not only to defend themselves, but also to conquer; they are full of ardour, energy, courage; these are indeed the true candidates for occultism.
As it takes many years to learn how to handle the different chemical substances, so also it is with occultism.
