The soul bound towards the eternal goal -- as it is called, the top of the mountains -- then proceeded towards the mountains. And before they reached the top of the mountains there was the cave, which is called heaven (in metaphysics, "capacity;" in Sanskrit, Akasha) which has the power of holding the soul from going to the top and using the soul for some purpose. And the soul which was bound for the eternal goal remained, so intoxicated by the ecstasy that it received from the plane of joy and the plane of wisdom. And as it ever happens that ecstasy produces purpose, so this joy resulted in a great purpose, in the birth of the Messenger, which in Sanskrit is called Bodhisattva. The Messenger was born of the soul's experience, the knowledge and the happiness, to bring good tidings to the world.
