Buddhist Wisdom/ The Middle path
Let me tell you about the middle path. Dressing in rough and dirty garments,
letting your hair grow matted, abstaining from eating any meat or fish, does not
cleanse the one who is deluded. Mortifying the flesh through excessive hardship
does not lead to a triumph over the senses. All self-inflicted suffering is
useless as long as the feeling of self is dominant.

You should lose your involvement with yourself and then eat and drink naturally,
according to the needs of your body. Attachment to your appetites–whether you
deprive or indulge them–can lead to slavery, but satisfying the needs of daily
life is not wrong. Indeed, to keep a body in good health is a duty, for
otherwise the mind will not stay strong and clear.

This is the middle path.
