To grasp the truth in the teachings of Scripture and our Church Fathers requires a calm and silent mind says, Basil the Great.
God who created us has given us the use of language, that we may reveal the plans of our heart to each other... Accordingly, since when our thought takes meaningful voice, as if carried in a ferry by our discourse, crossing the air it passes from the speaker to the hearer; and if it finds the sea calm and quiet, the discourse comes to anchor in the ears of the students as if in a tranquil harbors untroubled by storms; but if as a kind of rough upsurge the clamor of the hearers blows adversely, it will be dissolved as it is shipwrecked in the air. Therefore make it calm for the discourse through silence.... The word of truth is hard to catch.
