Then there is the essence of reason which is heavenly reason. It is that reason which not everyone understands. It is that reason which is discovered by the seers and sages, by the mystics and prophets within themselves. It is upon this reason that religions are founded. On the ground of this reason the ideas of mysticism and philosophy spring up as plants and bear fruits and flowers. When a pupil is expected to listen to the reason of his teacher, instead of disputing over it, it is in order to regard that heavenly reason behind it, and to know that there comes a time in one's life when one's eyes are open to the essential reason. It is that reason which is called Bodhisatva: Bodhi or Buddh meaning reason, and satva meaning essence.
