“Be mindful always of God. That is how our mind will acquire agility. Agility of mind comes from vigilance. Vigilance is passionate love for God. It is always having your heart and mind focused on Christ, even if you are engaged in other tasks. Vigilance requires love and yearning for Christ. You will acquire remembrance of God through the prayer ‘Lord Jesus Christ…through the prayers of the Church, through the hymns and through bringing to mind the acts of God and recalling passages from Holy Scripture and from other spiritual books.”
(Elder St Porphyrios, ‘Wounded by Love’)
