From The Magic and Mystery in Tibet:

 

... solitude and utter loneliness are far from being devoid of charm.

 

The trilogy, EXAMINATION, MEDITATION, UNDERSTANDING, takes a peculiar importance among the followers of [the Buddha's] "short path" and the intellectual activity of the disciple is exclusively toward results.

 

A declaration continually repeated by the Tibetan mystics:... it is necessary for you to realize that Gods, demons, the whole universe, are but a mirage which exists in the mind, "springs from it, and sinks into it."
