(69) What is night for all beings is the time of waking for the disciplined soul; and what is the time of waking for all beings is night for the sage who sees (or the sage of vision) When all beings are attracted by the glitter of sense-objects, the sage is intent on understanding reality. He is wakeful to the nature of reality to which the unwise is asleep or indifferent. The life of opposites which is the day or condition of activity for the unenlightened is night, a darkness of the soul to the wise. Cp. Goethe : "Error stands in the same relation to truth as sleeping to waking."
