The power of learning spiritual knowledge is to be able to know the soul in the light or darkness, as these are the substances the soul weaves around itself.

Just as the doctor of today must know how to navigate inside the living body in order to preserve the integrity of the body, so the soul too has an even greater and more delicate mystery to understand. 

Thoughts in relationship to time, and subtle substance changes of atmosphere, heat and cold and atmospheric pressures, speak another language to the student of the spirit.  It is this path of warmth and light in the cosmos that leads to the living spirit.

For the student of the spirit, his will is to seek and find the living spirit in and through nature. Only the light and the darkness of the world can reveal the truths of the soul in this living way. It is the greatest task set before the students. In accomplishments, the soul sheds layers upon layers of its thickened nature.  It must understand these as they fade in the cosmic world.

Knowledge becomes love.  The riddle is answered with 'how?'.

As the student must come to ponder the creation of man, he sees there the mystery of will and desire for creation. And like a candle made by a candle maker for the light it holds, so the souls of men are formed by the unknown and unseen power that creates it. But to know the creator of the candle, is the greatest of all mysteries to behold.
