From Chapter 8: Tertons and Doctrine-holders
One cannot judge Tertons as inauthentic because of their imperfect and mercurial character, even to the slightest extent. Guru Rinpoche himself has said:
The hidden enlightened beings appear in uncertain from; The fool-deceivers are great hypocritical mimics of the dharmic practitioner.Oh people! Do not take gold and dross as equal.
Amongst the false Tertons there were many who are harmonious with people, who seem to have disciplined conduct, and who are fortunate and charismatic. At the same time, among the authentic Tertons there are many who are loose in speech and behaviour and who, without the least hesitation, get involved in many activities that people will condemn. In that way the Tertons take many grave obstructions of the doctrine on themselves in the form of infamy and ill repute and they use them in the form of taking every experience in the great equal taste.
Likewise, there are Tertons who are unable to discover their Treasures and who have inauspicious retinues. There have been many celebrated Tertons, as illustrated by the lives of Padma Le drel Tsal and Sum tshog, who got diseases or died in an inauspicious manner: all these things happened for the sake of the same reason [taking obstructions upon oneself for the sake of the tradition].
