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 AvilaTo converse with You, O King of glory, no third person is needed, You are always ready in the Sacrament of the Altar to give audience to all. All who desire You always find You there, and converse with You face to face
Teresa of Avila
