The limited minds of the philosophers of old, such as Ptolemy and others, held that the realm of life and existence was confined to this terrestrial globe, and imagined that this infinite space was contained within the nine celestial spheres, all of which were void and empty. Witness how limited were their thoughts and how deficient their reasoning! The reincarnationists likewise imagine the spiritual worlds to be confined to those realms that the human mind can conceive. Some of them, such as the Druze and the Nuṣayrís, even imagine existence to be confined to this material world. What an ignorant supposition this is! For in this universe of God’s, which appears in the utmost perfection, beauty, and grandeur, the luminous bodies of the material universe are infinite. Pause to infer, then, how infinite and unbounded the spiritual realms of God, which are the very foundation, must be! “Take ye good heed, O people of insight!”159 <https://www.bahai.org/library/authoritative-texts/abdul-baha/some-answered-q...> Note: 159 Qur’án 59:2. ‘Abdu’l Bahá, Some Answered Questions.
