We can only start to grow in being when we take time to be still, even if it is only a few minutes each day, and open ourselves to God, like a flower opening its pedals to the sun, and receiving the strengthening rays of light. With continual practice, we can actually know that the spirit of Divine Love -- the Love of the omniscient creator of the entire universe -- is in us. ... Being still and experiencing the presence of God is the most important thing we can possibly do; for in this state of passivity we receive directive and strength for the day's action.
In that nocturnal tranquility and silence and in knowledge of the divine light, the soul becomes aware of Wisdom's wonderful harmony and sequence in the variety of her creatures and works. Each of them is endowed wíth a certain likeness of God and in its own way gives voice to what of God is in it. So creatures will be for the soul a harmonious symphony of sublime music surpassing all concerts and melodies of the world. Thus there ís in it the sweetness of music and the quietude of silence. AccordÍngly, she says that her Beloved is silent music because in the Beloved she knows and enjoys this symphony of spiritual music.
