Isha Upanishad
Life in the world and life in the spirit are not incompatible. Work, or action, is not contrary to knowledge of God, but if performed without attachment to results, is a means to it. Renunciation should be directed toward the ego. Renounce selfishness, not life. The goal of both life and of work is to know the divine God Self inside and out, and to realize, all is eternal divine oneness.
