There is an objective meaning, a literal salvation-oriented meaning intended by the author. And there is an intimate personal meaning, a spiritual sense that applies the text to me. Intuitively I dwell on the words. Either I hear the words coming from Christ to me or I address the words from myself to Christ. I make the biblical words my own, as when I pray a psalm.
Meditation makes the words one s own by identification.
Teresa knows that human beings think spontaneously in terms of time and space. It is extremely helpful to direct our attention to God in some localized place. So we think of God as beside us, in the tabernacle, at the crucifix, or wherever there is a sacred image. With Teresa we go to where God is. She preferred to ponder the divine indwelling, because it is so intimate to think of God within the self.
