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 AvilaWe may think it humility not to realize that the Lord is bestowing gifts upon us. Let us understand very, very clearly, how this matter stands. God gives us these gifts for no merit of ours. Let us be grateful to His Majesty for them, for, unless we recognize that we are receiving them, we shall not be aroused to love Him. And it is a most certain thing that, if we remember all the time that we are poor, the richer we find ourselves, the greater will be the profit that comes to us and the more genuine our humility.
Teresa of AvilaThey deceive themselves who believe that union with God consists in ecstasies or raptures, and in the enjoyment of Him. For it consists in nothing except the surrender and subjection of our will - with our thoughts, words and actions - to the will of God.
