When one gets to know God; when in the silence of prayer He overshadows our soul with a ray of His infinite beauty; when He overshadows our mind with His wisdom and power; when He inflames us with His goodness and mercy; then everything on earth is seen with sadness.
St. Teresa of Jesus of the Andes from a letter to her brother Lucho

Prayer to the Holy Spirit

Source of peace, Light,
come an enlighten me.
I am hungry, come and nourish me.
I am thirsty, come and quench my thirst.
I am blind, come and give me light.
I am poor, come and enrich me.
~Bl. Mary of Jesus Crucified (The Little Arab)

Those who practice prayer should have a special affection for him [St. Joseph] always... If anyone cannot find a master to teach him how to pray, let him take this glorious saint as his master, and he will not go astray.
St. Theresa of Jesus from her Autobiography

You ask me to assure you in my letters that I will always love you as a sister. Can you doubt it for even a moment? Can it be that you don't realize that my heart is being perfected by divine love and that, the more perfect it becomes, the more and greater love becomes? So never doubt that at every moment I'm praying for you, and my prayer is a song of love…
St. Teresa of Jesus of the Andes from her Letters

Vocal prayer must be accompanied by reflection. A prayer in which a person is not aware of to Whom he is speaking, what he is asking, who it is who is asking and of Whom, I don't call prayer... no matter how much the lips may move.
St. Teresa of Jesus

“because our Lord lives in our soul, His prayer dwells within us and it is there I want to abide without ceasing, as a little vase at the source and fountain of life, sharing this prayer with others by letting it overflow in ways of unending love”.
Bl. Elizabeth of the Trinity from The Charism of Her Prayer

Mental prayer in my opinion is nothing more than an intimate sharing between friends; it means taking time frequently to be alone with Him who we know loves us.
St. Teresa of Jesus

For my heart is always with Him, day and night it thinks unceasingly of its heavenly and divine Friend, to whom it wants to prove its affection.
~ Blessed Elisabeth of the Trinity
