Context

“My wisdom hath accumulated long like a cloud, it becometh stiller and darker. So doeth all wisdom which shall one day bear LIGHTNINGS.— Unto these men of to-day will I not be LIGHT, nor be called light. THEM—will I blind: lightning of my wisdom! put out their eyes! 8. Do not will anything beyond your power: there is a bad falseness in those who will beyond their power. Especially when they will great things! For they awaken distrust in great things, these subtle false-coiners and stage-players:— —Until at last they are false towards themselves, squint-eyed, whited cankers, glossed over with strong words, parade virtues and brilliant false deeds.” source
