A question may arise, why Manarnayakosh must be the mother, and Anandamayakosh and Vignanamayakosh must be the daughters. And the answer is that they are born of mind, born of mind and soul. If there were only the soul, there would be neither joy nor wisdom. Mind and soul both produce joy and wisdom. Therefore the latter are the daughters, because mind is the mother. The two lower planes are represented by the sons-in-law, because they were not directly born of mind and soul; it was a separate substance mind and soul have taken into their life. By this story the process is taught how the soul can journey from mortality to immortality, and what experiences the soul possibly has to have on its way. But when the Messenger is so created, then the Father -- the Soul -- rests in peace. It is therefore that the Messenger was called the Son, and the Original Soul the Father.
