FIRE
On higher planes everything is what down here we should call luminous, and above a certain level every thing may be said to be permeated by fire, yet not at all such fire as we know on the physical plane. What we call by that name down here cannot exist without something which either burns or glows, and it is only a kind of reflection or lower expression of a higher abstract thing which we cannot sense. Try to think of a fire which does not burn, but is in a liquid form, something like water. This was known to the followers of the first great Zoroaster, for they had this fire which no fuel on their altars, a sacred fire by means of which they symbolized divine life.
One way of reaching the LOGOS is along the line of fire, and the ancient Parsis knew this well, and raised themselves until they were one with the fire, so as to reach Him by way of it. The only way in which it can be done is through the assistance of certain classes of devas, but at this period of the world's history we are so grossly material that very few can stand the ordeal. The first Zoroaster had around him many who were able to take that way; and, though under present conditions our lower vehicles would probably be destroyed if we should make such an attempt, in new races and on other planets we shall be ale to take that way again. All this sounds strange and weird and incomprehensible, because it deals with conditions which are utterly unknown on the physical plane, but the student of occultism will find that in the course of his progress he has to face many things which cannot at all be expressed in words down here.
