Recognize the nature of your mind. Where do your thoughts come from, where do they reside, where do they go.
Easy to see the rapid movement of thoughts- from task to feeling to desire to discomfort to admiration to disdain. Adventitious is the mind, on an inner adventure it is.
Be persistent in your recognition of this adventurous mind. Watch the coming and going stream of thoughts and emotions. Aware of the flow, aware of the flow, aware of the flow. This is a powerful practice.
Knowing this you can know the suffering and happiness of all. Seed of your compassion and love.
