Before prayer, endeavour to realise Whose Presence you are approaching and to Whom you are about to speak, keeping in mind Whom you are addressing. If our lives were a thousand times as long as they are we should never fully understand how we ought to behave towards God, before Whom the very Angels tremble, Who can do all He wills, and with Whom to wish is to accomplish.
Teresa of AvilaThe true penance comes when God takes away the soul's health and strength for doing penance. Even though I have mentioned elsewhere the great pain this lack causes, the pain is much more intense here. All these things must come to the soul from its roots, from where it is planted.
Teresa of AvilaChrist does not force our will, He only takes what we give Him. But He does not give Himself entirely until He sees that we yield ourselves entirely to Him.
