" To have self-esteem and to function in society, ordinary people usually place their mind on something; they need to identify themselves with something. People with the least spiritual capacity identify their minds with fame, fortune, and other kinds of self-benefit. People with mediocre spiritual capacity identify their minds with their family, career, and relations with others. People with high spiritual capacity generate compassion and place their minds on the benefit of others. Only people with the most superior spiritual capacity have no mind to place anywhere. This is like the ox, whose mind, while having no fixed agenda, is free to respond to circumstances. "
