This is an excerpt from another letter of St. Paul of the Cross about the sea:
"The distractions of your work and other things are outside; with the eye of faith, with a glance of love, -- for lovers reach out to each other with such glances -- with a simple glance of faith and holy love, which takes place in a moment, all clothed with the gentle Jesus, the soul sinks and loses itself, I will put it that way, in the Immense Divinity, where no one can draw near.
I will put this in a parable, for our Divine Master spoke in parables. For example, finding myself on the shore of the sea, I take a drop of water, clinging to a finger of my hand, and I speak to this drop of water: "O poor little drop, where do you want to be?" Listen to the reply, "In the sea, in the sea," it says. What do I do? I shake my finger and let that poor little drop fall into the sea. Now I ask you: "Is it not true that you are that drop of water?" Certainly you are. But find it, if you have the mind to do so. You are lost in that great sea, your center. Oh, if it could speak what would it say? Draw the consequences, Signora Marianna, and apply the parable.
Lose sight of the sky and land, the sea and the sand, and everything created, and let this drop of soul that God has given you lose itself in its Origin, who is God, the Highest, the Almighty, and hidden there in the Divinity, allow love to do its work and be more passive than active.
You should understand that to make this flight of love, you need to go through the door that is Christ, as the Gospel teaches. The one who passes through this Divine Door finds oneself where the Lord is. He is in the bosom of the Father: "The Son of God, who is in the bosom of the Father." There he leads his dear lambs. Remain then, Marianna, "in the bosom of God," which is the true place of prayer, without images or figures, but in pure and naked faith and with a pure and clean love without dross."
