Thus he, being magnanimous, possessing, through knowledge, what is the most precious of all, the best of all, being quick in applying himself to contemplation, retains in his soul the permanent energy of the objects of his contemplation, that is the perspicacious keenness of knowledge. And this power he strives to his utmost to acquire, by obtaining command of all the influences which war against the mind; and by applying himself without intermission to speculation, by exercising himself in the training of abstinence from pleasures, and of right conduct in what he does; and besides, furnished with great experience both in study and in life, he has freedom of speech, not the power of a babbling tongue, but a power which employs plain language, and which neither for favour nor fear conceals aught of the things which may be worthily said at the fitting time, in which it is highly necessary to say them. He, then, having received the things respecting God from the mystic choir of the truth itself, employs language which urges the magnitude of virtue in accordance with its worth; and shows its results with an inspired elevation of prayer, being associated gnostically, as far as possible, with intellectual and spiritual objects.
