Bahá’u’lláh - Source of Knowledge

We have decreed, O people, that the highest and last end of all learning be the recognition of Him Who is the Object of all knowledge; and yet, behold how ye have allowed your learning to shut you out, as by a veil, from Him Who is the Dayspring of this Light, through Whom every hidden thing hath been revealed. Could ye but discover the source whence the splendour of this utterance is diffused, ye would cast away the peoples of the world and all that they possess, and would draw nigh unto this most blessed Seat of glory.
