November 29

Know thou, verily, man before reaching (spiritual) maturity passes his days and only apprehends trivial things which are clear on account of their exoteric indications, but when he attains full development, then he grasps the reality of things and their esoteric facts. Every day after maturity is equivalent to one year before it, on account of (man’s) perception, understanding, apprehension and discoveries.

Now, thou hast reached development and apprehended the degree of maturity: Gaze at the grades of the existence, the realities of beings, the allegories in the epistles of God, and the mysteries in the Old and New Testament. By the life of Baha, the covering will be removed from off thee (i.e., facts will be unfolded to thee), and thou wilt be informed of that which all the philosophers and wise men are unable to apprehend. Verily, this is a gift which God assigns only to such of His chosen servants as He willeth. Verily, thy Lord will inspire thee with the mysteries of God, the Protector, the Self-subsistent.
