And then as we do this, we start becoming aware of something even deeper inside is the really the quality of our inner life. The state of the mind, the state of the heart, the quality. And we become aware there are also if it's more in the surface of things, and get caught up in the partial parts of the mind of greed, hatred and delusion. Or we're really connecting to something deeper and deeper, fuller, about the mind, the heart, the inner life. Sometimes it can no longer be called an inner life because awareness starts feeling expansive, open, it has no boundaries anymore. And the mind, state of mind, the inner life, starts feeling expansive, wonderful, exalted. Can feel very settled, very much at peace, and can even start feeling liberated and free. And this sense of what inner freedom feels like, where the heart, the mind is no longer caught and trapped and preoccupied is a wonderful feeling. And start feeling that becomes a reference point for the fourth foundation of mindfulness, which has a lot to do, it's all about, what is it that, how is it that we lose our freedom, that sense of freedom, that inner inner quality of being unoppressed, unburdened, unfrayed, uncontracted? Just free and open, expansive. So what is it that in that awakening, that freedom is kind of a light, Then what is it that dims that light? And what is it that brightness that light even more? What brings greater freedom? And so the fourth foundation of mindfulness is really starting to notice this for ourselves. And not reading a book about what freedom is and loss of freedom, but really reading the book inside of ourselves. Having the inner reference point and feeling the difference. Making that distinction between dimming of the light and the growing of the light. Or contracting and expanding, being caught and being limited in our awareness and our thoughts and what we do. And becoming more unlimited and expansive and free.
