Your nights and days will be filled with it. ...Many confuse silence with solitude. Solitude is being alone with God, waiting for God. But silence is an immense sea into which you enter and never leave. And once you have plunged into this silence, you will always be silent.
Mystical wisdom derives from an ardent desire to abandon normal intellectual functions so that divine insight may enlighten this ardor and add to it another fire, much stronger, which lifts the burning soul towards an even deeper wisdom.
