"The world outside is as different from this world as this world is different from that of the child while still in the womb of his mother." says Bahá'u'lláh. [See: anthology of the writings of Bahá'u'lláh, © 1952, 1970, 1990, National Spiritual Assembly of the Bahá'ís of the United States, No. LXXXI page. 156.] In this diagram I have tried to draw a list of some of the implementations of this quote. "The union of the human soul" by Adib Taherzadeh [1992 Ronald George) gives you a much deeper understanding of this topic.
