Pema Chodron writes in The Wisdom of No Escape,

What you will discover as you continue to study the dharma to practice meditation is that nothing you have ever heard is separate from your life. Dharma is the study of what is, and the only way you can find out what is true is through studying yourself. The Zen master Dogen said, “To know yourself or study yourself is to forget yourself, and then you become enlightened by all things.
