Who is there who would not cry in your arms without instantly receiving your immaculate kisses of love and comfort? If he be a sinner, your caresses will soften him. If one of your devoted ones, your presence would enkindle the living flame of divine love. If he be poor, you with your powerful hand will aid him and show him his true homeland. If rich, you will sustain him with your breath against the dangers of his very agitated life.
~St. Teresa of Jesus of the Andes from her Diary

"In the presence of Jesus in the Holy Sacrament we ought to be like the Blessed in heaven before the Divine Essence."
~St. Teresa of Jesus

...One love in them all makes of them one Lover,

and the Lover is the Beloved in whom each one lives.

For the being that the three possess each of them possesses,

and each of them loves him who bears this being.

Each one is this being, which alone unites them,

binding them deeply, one beyond words....

~St. John of the Cross from Romance on the Gospel text In principio erat Verbum, regarding the Blessed Trinity. 

"At the time of Holy Communion I sometimes picture my soul under the figure of a little child of three or four years, who at play has got its hair tossed and its clothes soiled. These misfortunes have befallen me in battling with souls. But very soon the Blessed Virgin hastens to my aid: quickly, she takes off my dirty little pinafore, smoothes my hair and adorns it with a pretty ribbon or simply with a little flower... and this suffices to render me pleasing and enables me to sit at the Banquet of Angels without blushing."
~St. Thérèse of the Child Jesus and the Holy Face, from Counsels and Reminiscences

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

O Consuming Fire, Spirit of Love, descend into my soul and make all in me as an incarnation of the Word, that I may be to Him a super-added humanity wherein He renews His mystery; and You, O Father, bestow Yourself and bend down to Your little creature, seeing in her only Your beloved Son in whom You are well pleased.
~Blessed Elizabeth of the Trinity from Elevation to the Most Holy Trinity

We can never have too much confidence in the good God who is so powerful and so merciful. We obtain from him as much as we hope for.  
~St. Thérèse of the Child Jesus and the Holy Face

“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

To the extent that we know this God made man, we come to love him madly. I would like you to know him in order to be truly in love with him… How not to love this Jesus of our soul? He is uncreated Beauty, eternal Wisdom, Goodness, Life, Love… Oh! Love Jesus. Who can love you better? He thirsts for your heart.
~St. Teresa of Jesus of the Andes (Letter 136)

It does us much good to look into the soul of saints and then to follow them through faith right up to Heaven; there, they are all luminous with the light of God, whom they contemplate face to face for all eternity!… The Heaven of the saints is our homeland. It is the Father’s House where we are awaited, where we are loved, where one day we, too will be able to fly and rest in the bosom of Infinite Love!  
~Bl. Elizabeth of the Trinity, Letter 184

 Do not engage yourself in something less or pay heed to the crumbs that fall from your Father's table. Go forth and exult in your Glory! Hide yourself in it and rejoice, and you will obtain the supplications of your heart.

St. John of the Cross, from Prayer of a Soul Taken in Love

Accustom yourself to make many acts of love, for they enkindle and melt the soul.
St. Teresa of Jesus ~ from Maxims for Her Nuns in The Complete Works

Everything else we do is a means to an end. But love is an end already, since God is love.

~ St. Teresa Benedicta of the Cross (Edith Stein)

Who can free themselves from lowly manners and limitations if you do not lift them to yourself, my God, in purity of love? How will human beings begotten and nurtured in lowliness rise up to you, Lord, if you do not raise them with your hand that made them?
St. John of the Cross, from Prayer of a Soul Taken in Love

I am happy and shall never cease to be so because I belong to my God. At every moment I find in him my heaven and an eternal and immutable love. I don't desire anything but him and this love grows in my soul inasmuch I see myself introduced in the the bosom of his divine love and adorable perfections.
~St. Teresa of Jesus of the Andes (Letter 148)

Since He is there, let us keep Him company, as a friend with a friend. This Divine union is quite interior and it is the essence of our life in Carmel. It is what makes our solitude so dear to us, for as our Father St John of the Cross says, two hearts that love each other prefer solitude to everything else.
~Bl. Elizabeth of the Trinity from The Charism of Her Prayer

Meditative prayer is one stage higher[than vocal prayer]. Here the spirit moves more freely without being bound to specific words. It immerses itself, for example, in the mystery of the birth of Jesus. The spirit's imagination [Phantasie] transports it to the grotto in Bethlehem, seeing the child in the manger, the holy parents, the shepherds, and the kings. The intellect ponders the greatness of divine mercy, the emotions are seized by love and thankfulness, the will decides to make itself more worthy of divine love. This is how meditative prayer involves all the soul's powers and, when practiced with faithful persistence, can gradually remake the whole person. However, the Lord has yet another way of rewarding fidelity in meditation: by elevation to a higher manner of praying.
~St. Teresa Benedicta of the Cross from Love for Love

..."vocal" prayer is not to be understood as simply saying words. If the mere words of a prayer alone are said without the soul's raising itself to God, this is only an outward show and not real prayer. The designated words, however, support the spirit and prescribe to it a fixed path.
~St. Teresa Benedicta of the Cross from Love for Love

The feeling remains that God is on the journey too.
St. Teresa of Jesus

Oh, how I suffer now when I recall how I forgot the longings of my childhood! My God, since you seem to have decided to rescue me, let it be your glorious will to do so.... Why did this soul, which you have selected for your habitation and showered with grace, become spotted like this? I feel great pain remembering it, for I know very well that I alone was guilty. You, Oh Lord, have left nothing untried to open my eyes ever since my youngest days.
~ St. Teresa of Jesus 

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

All things must come to the soul from its roots, from where it is planted.

~St. Teresa of Jesus
