The path and the journey are not the same thing, and the rose will show you the difference. It has to go on being a rose whatever the weather does. The one in the photograph is blossoming in snow.

Two things here cost nothing. A meditation, The Aether at the Threshold. And The One Voice, the opening chapter of The Ego on a String — the whole chapter, not a sample of one.
Everyone strays. That is not the interesting part.
The interesting part is that everyone comes back, and that the coming back is not a failure of the journey but the shape of it. The soul needs trials before it reaches any height. A person arrives at each new stage of seeking having arrived at it before — it is never the first time — and the eyes of the spirit see all of it, and are looking for him even now, wondering whether he is ready to go on.
A teaching like this one works through pictures and symbols, because that is what wakes the inner eye. The path is only partly outside you. The other part is inside, and it has to be recognised rather than walked.
Now something from the ground itself.
A river cannot run straight. Any bend, however slight, throws the current against one bank and away from the other. The outside of the bend erodes, the inside silts, and the bend deepens itself — so the smallest accident of the ground becomes, given time, a loop. Men have straightened rivers. The straightened ones silt, flood, and work their way back into curves.
The straight line is the shorter distance. It is not the way water goes anywhere.
The path and the journey are symbolised by a serpent on a rod. The rod is not the law, though it is not far from it. The rod is truth, and the blood knows truth through the iron awakened in it — as a line is drawn between us and any distant thing we look at, so the blood draws the student toward the light-blood of the Master of Auras and Light in the higher astral world. He is the teacher a student must learn from, to cleanse the blood and raise it into light.
Raising it is called the Raising of the Serpent. It is the light of the astral body rising in the spinal column, the measure by which the soul weighs its own substances and heals itself into a real soul-self. As the serpent comes out of the spine and lies over the ground of the world, it points out the lines of the spiritual realm rising from below — and the astral substance of the earth is drawn up with the student, the way a tree goes up.
Anyone willing to do the work will reach the goal. What is taught here is already in you; the teaching only makes it visible. Each person brings his own difficulty, and the road can be shortened, because the teacher is always on it and always watching.
Anyone who goes off the path comes back to it. The teacher is there to greet him again and again. When you are close to the path and exhausted by misery, he knows how to bring you back to your hope and show you where to rejoin the road you remember.
The sign of the teacher is the man by the river.
