A disciple who is trained by a man of God will have a pure and purified spirit. But he who is trained by an imposter and hypocrite and who learns theory from him will be just like him: despicable, weak, incapable, morose, without any exit from uncertainties, and deficient in all his senses. “As for the unbelievers — their protectors are idols, that bring them forth from the light into the shadows.” (Qur’an 2:257).

[From the "Fihi ma fihi," translated by W. C. Chittick in "The Sufi Path of Love: the Spiritual Teachings of Jalaluddin Rumi," p. 145]

If the character of someone trained by an impostor is to be:

despicable, weak, incapable, morose, without any exit from uncertainties, and deficient in all his senses.

Then the qualities of a properly spiritually trained individual is to be:

dignified, honored, strong, capable, bright, absolutely certain, completely aware of all his senses.
