I also found these quotes from Saint Thérèse of Lisieux on Wikipedia. They remind me of Eastern approaches to spirituality. I also like simple approaches myself.
Sometimes, when I read spiritual treatises in which perfection is shown with a thousand obstacles, surrounded by a crowd of illusions, my poor little mind quickly tires. I close the learned book which is breaking my head and drying up my heart, and I take up Holy Scripture. Then all seems luminous to me; a single word uncovers for my soul infinite horizons; perfection seems simple; I see that it is enough to recognize one’s nothingness and to abandon oneself, like a child, into God’s arms. Leaving to great souls, to great minds, the beautiful books I cannot understand, I rejoice to be little because only children, and those who are like them, will be admitted to the heavenly banquet.
Here is what she said about her approach to prayer:
For me, prayer is a movement of the heart; it is a simple glance toward Heaven; it is a cry of gratitude and love in times of trial as well as in times of joy; finally, it is something great, supernatural, which expands my soul and unites me to Jesus…I have not the courage to look through books for beautiful prayers…I do like a child who does not know how to read; I say very simply to God what I want to say, and He always understands me.
