What is the fifth Mindfulness training? What does Hanh say about alcohol in this section?

The fifth Mindfulness training is associated with ingesting healthy foods and only those that preserve peace, well-being and joy without damage to our selves or society. Hanh discourages drinking of any alcohol in the interest of ourselves and others, using mindful consumption to stop the course of "destruction for our body, our consciousness, and the collective body and consciousness of our society."
