Silence is the maturation of wisdom.
You must accept the truth from whatever source it comes.

The physician should not treat the disease but the patient who is suffering from it
No disease that can be treated by diet should be treated with any other means.
The more necessary a thing is for living beings, the more easily it is found and the cheaper it is; the less necessary it is, the rarer and dearer it is.
