The Eleventh Mindfulness Training: Right Livelihood
Aware that great violence and injustice have been done to the environment and society, I am committed not to live with a vocation that is harmful to humans and nature. I will do my best to select a livelihood that helps realize my ideal of understanding and compassion. Aware of global economic, political and social realities, I will behave responsibly as a consumer and as a citizen, not investing in companies that deprive others of their chance to live.
