The most powerful prayer, one wellnigh omnipotent, and the worthiest work of all is the outcome of a quiet mind. The quieter it is the more powerful, the worthier, the deeper, the more telling and more perfect the prayer is.
Meister EckhartLet God operate in thee; Hand the work over to Him and do not disquiet thyself as to whether or no He is working with nature or above nature, for His are both nature and grace.
Meister EckhartDo not think that saintliness comes from occupation; it depends rather on what one is. The kind of work we do does not make us holy, but we may make it holy.
Meister EckhartBehold how all those people are merchants who shun great sins and would like to be good and do good deeds in God's honour, such as fasts, vigils, prayers, and similar good deeds of all kinds. They do all these things so that our Lord may give them something, or so that God may do something dear to them. All these people are merchants.
Meister Eckhart
