Continual reflection on the Scriptures is light for the soul, because they imprint on the intellect recollections helpful for guarding against the passions and for continuance with God through love and the purity of prayer; further, it makes straight before us the path of peace trodden by the footsteps of the saints. Do not, however, set your hopes upon the notations of the verses when in your prayers or hourly reading they are not attended by great alertness and constant contrition. Accept without fail words spoken from experience, even if the speaker is unlearned; for the treasuries of great kings of the earth do not despise the addition of a beggar’s obol, and by brooks great rivers are filled and their flow is mighty.
St Isaac the Syrian. From Homily Fifty-Four.
