To argue over who is the more noble is nothing more than to dispute whether dirt is better for making bricks or for making mortar.

I don't know what heavy penance could have come to mind that frequently I would not have gladly undertaken rather than recollect myself in the practice of prayer.

I am afraid that if we begin to put our trust in human help, some of our Divine help will fail us.

Souls who do not practice prayer are like people whose limbs are paralyzed.

In order to profit from this path [of prayer] and ascend to the dwelling places we desire, the important thing is not to think much but to love much; and so, do that which best stirs you to love.

Lord, how Thou dost afflict Thy lovers!

A slight failing in one virtue is enough to put all the others to sleep.
