O abyss! O eternal Godhead! O deep sea! What more could you have given me than the gift of your very self?

Quotes from the same author

O Trinity, eternal Trinity! Fire, abyss of love... Was it necessary that you should give Even the Holy Trinity as food for souls?... You gave us not only your Word Through the Redemption and in the Eucharist, But you also gave yourself In the fullness of love for your creature.
 St. Catherine of Siena
This my goodness does to endow the souls of the just more fully with spiritual riches when for my love they are stripped of material goods because they have renounced the world and all its pleasures and even their own will. These are the ones who fatten their souls, enlarging them in the abyss of my charity. Then I become their spiritual provider. The Holy Spirit becomes their servant.
 St. Catherine of Siena
When it seems that God shows us the faults of others, keep on the safer side-it may be that your judgment is false. On your lips let silence abide. And any vice that you may ascribe to others, ascribe at once to them and yourself, in true humility. If that vice really exists in a person, he will correct himself better, seeing himself so gently understood, and will say of his own accord the thing that you would have said to him.
 St. Catherine of Siena
The city is the image of the soul, the surrounding walls being the frontier between the outward and inward life. The gates are the faculties or senses connecting the life of the soul with the outward world. Living springs of water rise within it. And in the centre, where beats the heart, stands the holy sanctuary.
 St. Catherine of Siena
Do not be satisfied with little things, because God wants great things!
 St. Catherine of Siena
