On Detachement

The man who has submitted his will and purposes entirely to God, carries God with him in all his works and in all circumstances. Therein can no man hinder him, for he neither aims at nor enjoys anything else, save God. God is united with Him in all his purposes and designs. Even as no manifoldness can dissipate God, so nothing can dissipate such a man, or destroy his unity. Man, therefore, should take God with him in all things; God should be always present to his mind and will and affections. The same disposition that thou hast in church or in thy cell, thou shouldst keep and maintain in a crowd, and amid the unrest and manifoldness of the world.
Meister Eckhart
