6.6.1 "Of coagulated milk, my dear, when churned, that which is the finest essence all moves upward; it becomes butter.

6.6.2 Even so, verily, my dear, of food, when eaten, that which is the finest essence all moves upward; it becomes the mind.

6.6.3 Of water, my dear, when drunk, that which is the finest essence all moves upward; it becomes the breath.

6.6.4 Of heat, my dear, when taken in, that which is the finest essence all moves upward; it becomes the voice.

6.6.5 For, my dear, the mind consists of food; the breath consists of water; the voice consists of heat."

"Do you, Sir, cause me to understand even more."

"So be it, my dear," said he.
