Thomas À Kempis said this quote

“ Pardon me also, and deal mercifully with me, as often as I think of anything besides You in prayer. For I confess truly that I am accustomed to be very much distracted. Very often I am not where bodily I stand or sit; rather, I am where my thoughts carry me. Where my thoughts are, there am I; and frequently my thoughts are where my love is. That which naturally delights, or is by habit pleasing, comes to me quickly. Hence You Who are Truth itself, have plainly said: 'For where your treasure is, there is your heart also.' If I love heaven, I think willingly of heavenly things. If I love the world, I rejoice at the happiness of the world and grieve at its troubles. If I love the flesh, I often imagine things that are carnal. If I love the spirit, I delight in thinking of spiritual matters. For whatever I love, I am willing to speak and hear about. ”
