There is a valley, lying at a rather high altitude in the foothills of the Himalayan-Tibet ranges. It is surrounded by high mountains on all sides except towards the northeast, where there is a narrow opening in the mountain ranges. The valley is bottle-shaped in contour, with the neck of the bottle to the northeast, and it widens very considerably towards the south. Up towards the northern end, close to the neck of the bottle, there a huge flat rock. There are no trees or shrubs in the valley, which is covered with a kind of coarse grass.
Approaching the time of the full moon of Taurus, pilgrims from the surrounding districts begin to gather. The holy men and the lamas find their way into the valley and fill the southern and the middle parts, leaving the northeastern end relatively free. There, so the legend runs, gathers a group of those great Beings Who are the Custodians on Earth of God's Plan for our planet and for humanity.
