Moreover, all are unanimous in declaring the first method the safer of the two. A pure life, the performance of good deeds, righteousness, compassion… - Alexandra David-Néel

Silence was not compulsory as it is amongst the Trappist, but the monks seldom spoke. They did not feel the need of talking nor of spending their energy in outward manifestations. Their thoughts remained fixed on secret introspections and their eyes had the inward gaze of the Buddha's images.

Whatever may be the causes at work, telepathic transmissions, either conscious or unconscious, seem to occur rather frequently in Tibet. Regarding my own experience, I am certain that I did receive on several occasions telepathic messages from lamas under whom I had practiced mental or psychic training. It may even be that the number of these messages has been larger than I suspect. However, I have only retained a few cases in which the lama afterwards inquired if I had understood what he meant to tell at a given time.

The object of these teachings is not to amuse the simple-minded, those charitably called in the Tibetan Scriptures the "children", it is meant for the strong to make them stronger, for the intelligent to make them more intelligent, for the shrewd to develop their shrewdness and to lead them to the possession of transcendent insight (lhag thong) which constitutes the real enlightenment. p. 11
