“But this physical body, which is believed to be of so little importance by those who love to dream about the mysteries of the spirit, is the most secret and valuable thing. It is the true "stone which the builders rejected," but which must become the corner-stone of the temple. It is the "stone" which is considered worthless by those who seek for a God above the clouds and reject Him when He enters their house. This physical body is not merely an instrument for divine power, but it is also the soil from which that which is immortal in man receives its strength.”
