…the life of man is wholly subject to danger and impermanency. A person cannot put his assurance even in one moment's continuity. Notwithstanding this, the nations of the world, deceived by the mirage of superstition, imagine themselves secure in the heavenly way. Alas! Alas! Former communities in bygone ages entertained the same perishing thoughts; but by one of those periodical fluctuations they were all hidden under the ground, and afflicted with deprivation and loss, except those souls who had become pure evanescence and had arisen with a great self-abnegation in the path of God. Such souls shine forth as brilliant stars from the horizon of the Ancient Glory, and the results which emanated from their lives in succeeding ages and cycles are the proofs of this statement.
