O you People of the Truth! do not ally yourselves with evil. Choose wisely. For this shall be the test of your faith and thereupon shall rest the judgement of your life in this World. As all worldly things have a shadow, so Truth on Earth has a shadow too. Only in My Abode of Light where all is bright and clear there is no shadow, no Untruth and no lie. But on Earth, where light is obscured by shadow, the Untruth finds easy pray. For this reason, on Earth, some must die in order that others may prevail. Let every man strive to overcome the enemies of Truth. But he
who conquers both the outward and inward enemies, namely, fear, attachment and the rest, is by far the best. He becomes a Perfect One in this very lifetime.
