No one can give birth to a soundly constituted higher self whose life in thought and feeling, in the physical world, is not sound and healthy.

Rudolf Steiner, How to Know Higher Worlds [Bookshop, Amazon, Publisher]

Hermetic quote Steiner How to Know Higher Worlds give birth to a soundly constituted higher self

Consider also:

  1. “I am indeed the Angel of Death; but I am at the same time the bearer of a higher life without end. Through me thou wilt die with thy body still living, to be reborn into an imperishable existence.”
  2. “The Ceremony of our first degree, then, is a swift and comprehensive portrayal of the entrance of all men into, first, physical life, and second, into spiritual life; and as we extend congratulations when a child is born into the world, so also we receive with acclamation the candidate for Masonry who, symbolically, is seeking for spiritual re-birth”
  3. “But upon entering this world, the soul must needs assume material form; in other words it takes upon itself a physical body to enable it to enter into relations with the physical world, and to perform the functions appropriate to it in this particular phase of its career. Need I say that the physical form with which we have all been invested by the Creator upon our entrance into this world, and of which we shall all divest ourselves when we leave the Lodge of this life, is represented among us by our Masonic apron?”
  4. “I am that very being who shaped my body out of thy good and evil achievements. My spectral form is woven out of thine own life’s record.”
  5. “Natural, rational life is the basis of all genuine spiritual development”
