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.
“After I have said that I want all beings to become buddhas, I get unhappy when harmdoers get even minimal prosperity or honor. This is extremely contradictory.’ You must eliminate your jealousy regarding any sort of attainment by other persons and delight in it from the depths of your heart. Otherwise your Bodhicitta and the achievement of the welfare and happiness of beings are nothing but words.”
-Lam Rim Chen Mo
