In detachment…

In detachment the spirit finds quiet and repose, for coveting nothing, nothing wearies it by elation, and nothing oppresses it by dejection, because it stands in the center of its own humility.
–Evelyn Underhill (1875-1941)

Heavenly realities…

Tie the leg of a sparrow to the ground, and no matter how hard it tries to fly, it will be fastened to the earth. In the same way, if your intellect tries to fly up to the mystical knowledge of heavenly realities but has not yet been freed of obsessive passions, it will remain tied fast to the earth.
–Saint Maximos the Confessor (580-662)
