There's a Kagyu story about a Lama and his three students. The Lama was kind hearted and knowledgeable but not Enlightened. All his claims of normalcy were ignored by his students as modesty, who practiced seeing him as Enlightened and thus quickly surpassed their teacher and gained Enlightenment. Whereupon they saw their guru as a ordinary human and became his gurus.
"All memories and thoughts are the union of emptiness and knowing, the Mind.
Without attachment, self-liberating, like a snake in a knot.
Through the qualities of meditating in that way,
Mental obscurations are purified and the dharmakaya is attained."
-Ra Lotsawa, All-pervading Melodious Drumbeats
"You must experience that the various thoughts, in whatever form they arise, are an empty appearance and not a definable entity."
-Clarifying the Natural State pg. 33
