So, then, should a man have no imagining in his mind? One cannot be without imaginings. Should one not breathe? One cannot do without breathing. The best way is to make a medicine of the illness. Since heart and breath are mutually dependent, the circulation of the light must be united with the rhythm of breathing. For this, light of the ear is above all necessary. There is a light of the eye and a light of the ear. The light of the eye is the united light of the sun and moon outside. The light of the ear is the united seed of sun and moon within. The seed is thus the light in crystallized form. Both have the same origin and are different only in name. Therefore, understanding (ear) and clarity (eye) are one and the same effective light.
