The document discusses two modes of the mind: the doing mode and the being mode. The doing mode involves problem-solving, rumination, and making things the way we think they should be, which can worsen negative emotions. The being mode is awareness and mindfulness - paying attention to the present moment without judgment. Mindfulness can help disengage thoughts, live in the present, and stop negative mental patterns that lead to depression. The rest of the program teaches how to cultivate mindfulness as a skill to change one's life.
