" There be many gurus, and some good ones whom it is no great task
to differentiate, seeing that those who make the loudest claim
are least entitled to respect. They who are the true guides into
Knowledge know that nothing can be taught, although the learner
easily can be assisted to discover what is in himself. Other than
which there is no knowledge of importance, except this: that what
is in himself is everywhere.--From The Book Of The Sayings Of
Tsiang Samdup "
