Most Mysterious Sights
When the intelligent and animal souls are held together in one embrace, they can be kept from separating.
When one gives undivided attention to the (vital) breath, and brings it to the utmost degree of pliancy, he can become as a (tender) babe.
When he has cleansed away the most mysterious sights (of his imagination), he can become without a flaw.
Lau-tzu, Tao-te Ching
