The Inner voice (n.) is best handled like a dialogue between two people with equal rights: write it down, answer it from the ego, and bear the long conflict that follows.
The Inner voice (n.) needs no insanity to be heard; the hybris lies in saying "It is only my own thoughts!" about thoughts you had never consciously thought.
An Inner voice (n.) is taken either for undiluted nonsense or for the voice of God; it occurs to no one that something valuable might lie in between.
An Inner voice (n.) makes a personality of whoever consciously assents to it and sweeps away whoever succumbs to it — the genuine personality voluntarily sacrifices himself and lives individually what would ruin the group lived unconsciously.
An Inner voice (n.) usually whispers something negative, even evil — the community's evil in an individual form — tempting us to succumb; only by succumbing in part, without being swallowed, can we find the evil was a bringer of healing: it is a Lucifer in the strictest sense.
The Inner voice (n.) must be heard attentively but critically, since the divine influx flows in right and left streams of opposites; identifying one's mind with it risks a Messianic sense of mission and tyranny over others.
