When the man becomes conscious of the Lord’s Presence, he must let his work alone and worship Him. All his powers must be still, and there must be calm. Otherwise the works of man [in meditation] would be but a hindrance, and his good works also; for he must do nothing but submit himself to God. But when a man is again left to himself [and contemplation ceases] and he is no longer conscious that God is working in him in any way that he can clearly recognize, then he must begin again to work diligently [at meditative prayer], and to discipline himself in holiness. Thus the man will sometimes work [in meditation], and sometimes rest [in contemplation], as he is moved by God and entreated. Everyone must do as it seems best to him, either working or resting, so that he may be drawn to God.
Johannes Tauler OP (1300–1361)
