People in the world pay little heed to reason where their own interests are involved.
Teresa of AvilaKeep this in mind, for it is very important advice, so do not neglect it until you find you have such a fixed determination not to offend the Lord that you would rather lose a thousand lives and be persecuted by the whole world, than commit one mortal sin, and until you are most careful not to commit venial sins.
Teresa of AvilaDiscontent with this world gives such a painful longing to quit it that, if the heart finds comfort, it is solely from the thought that God wishes it to remain here in banishment.
Teresa of AvilaBefore 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 Avila
