Why is it that you're here? From where does your urge for esoteric development come? About 4000 years ago, and so before the Event of Golgotha, the etheric body enlivened the physical body in such a way that not all of the etheric body's forces were used to permeate the physical body, and it was to these forces that an esoteric turned, with these he turned to spiritual worlds. Then about 3000 years ago, all etheric bodies had sunk into the physical bodies, especially in Greece, and those who developed the greatest things in the physical realm felt that the spiritual world was a realm of shades. But now the physical body no longer absorbs all of the etheric body's forces, it rejects them, it is withering, for we are past the middle of earth evolution, and it's only through these force that the physical body can no longer take in that we can live in the spiritual world. And you who felt this urge for esoteric development, who were not satisfied with mere physical life and knowledge, you sensed these unused forces in you; they drove you to seek an esoteric life.
What's the difference between esoteric and exoteric? In exoteric life we get communications that are taken from esoteric life as food for our souls. In esoteric life we try to look into the worlds from which esoteric communications are taken ourselves.
What's given here is not just communications — it's advice that flows from spiritual inspiration. It's not just words, concepts, ideals — it's words, concepts and ideals that are permeated with life, life germs that are sunk into our etheric forces and that should blossom there — they're realities. They've been tested repeatedly by those whom we call the masters of wisdom and of the harmony of feelings.
Esoteric is a source of life and of forces that flow through the world and that should also stream through us. And so every Sunday morn at 9 o'clock you should meditate on: In the Spirit of Mankind I feel united with all esoterics. When we begin our exercises it's of great importance that we first create inner quiet. It can be attained through patience. The only thing we have to combat if the thought: I won't attain it. We should reject this as a temptation. And even if it takes ever so long, the time will come when our thought horizon will become clear, if we just push away the sense impressions and thought that distract us with all the willpower that we muster. We should let the formulas and symbols live in us vigorously and energizingly, shouldn't form thoughts about them but should experience them and feel them to be like an inner light. They must take hold of us strongly, for they are drawn from the unspeakable word that has creative power. This is the Indians' mahavach; it's inspirations from words that sound through spiritual worlds; it's supposed to radiate in us like an inner sun.
Then we must create an inner void by erasing and suppressing everything that arises from memory, including theosophical contents, and just wait for what can rise in our soul — either something entirely new that we've never heard or had a inkling of, or a lively vision of occult facts that we received in exoteric life. Much more strength is needed for independent discoveries than for an intelligent understanding of the Pythagorean theorem or some other already found fact. What's communicated to us now we can also find ourselves, but probably only after 25 incarnations. We have the duty to work a long with the present state of evolution by shortening the path as much as possible.
