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
