Whatever process you use in alchemy you will always have to go by steps. All these levels of energy exist in everything, in the mineral, vegetable, and man. To understand what is coming, that will be spoken of Sunday, we will only lightly speak of certain things, because today is a preparation so that you can understand what we will do, then we will go and do it. Every level constitutes what we call an inner world or a level in the universe. In each of these levels there exists things and elements that exist on the earth level.
Energy is in degrees and it can match matter and can act on it, even in very subtle states in form.
In fact the real work of alchemy or qabala and the real initiation is to go up the levels of the conscious of man, up one by one, so as to become conscious of these inner worlds. When dealing with alchemy or qabala it's important to know that the energy comes down always by the same way. It is something you have to remember when you will have complex experiments. That's the general aspect of energy. These energies have several aspects we can use in alchemy.
