There is no need for us to roam about heaven and earth in quest of God, or to send forth our minds into diverse places in search of Him. Therefore, purify your soul, O man, and drive away from you all cares which concern things outside your nature, and shroud your soul's perceptions and movements with the veil of chastity and humility: by this means you will discover Him that is within you, since 'mysteries are revealed to the humble' (Sir. 3:19).
Homily 4 (pp. 148-149)
