Buddhism is presented in several branches in various ways highlighting various aspects and Chan/Zen Buddhism has a very captivating and elegant simplicity. I'll site few quotes below:

>The mind is an uncertain thing. This body is uncertain. Together they are impermanent. Together they are a source of suffering. Together they are devoid of self. These, the Buddha pointed out, are neither a being, nor a person, nor a self, nor a soul, nor us, nor they. They are merely elements: earth, water, fire, and wind. Elements only! When the mind sees this, it will rid itself of attachment which holds that ‘I’ am beautiful, ‘I’ am good, ‘I’ am evil, ‘I’ am suffering, ‘I’ have, ‘I’ this, or ‘I’ that. You will experience a state of unity, for you’ll have seen that all of mankind is basically the same. There is no ‘I’. There are only elements. - Ajahn Chah: Bodhinyana

>The Unborn is the ground of everything; the Unborn is the beginning of everything. Because there is no ground for anything outside of the Unborn and because before the Unborn there was no beginning for anything, the Unborn is the foundation of all Buddhas. - Bankei (1622-1693)

>The perfect person has many different aspects but at heart he changes not. To understand the world he assumes its appearances but his heart remains centered on the One. Within he is stable, outwardly he bends and straightens like a bow - Wen-tzu

>Neither by words nor by the patriarch; Neither by colors nor by sound was I enlightened. But, at midnight, when I blew out The candle and went to bed, Suddenly, I reached the dawn. Profound quietude delivered me To the transparent moonlight. After enlightenment one understands That the Six Classics contain not even a word. - Wang Yang-ming (1472-1529)

>If you do not spontaneously Trust yourself sufficiently, You will be in a frantic state, Pursuing all sorts of objects And being changed By those objects, Unable to be independent. - Linji (d.867)

>Keys of Zen Mind

When you find peace and quiet in the midst of busyness and clamor, then towns and cities become mountain forests; afflictions are enlightenment, and sentient beings realize true awakening. These sayings can be uttered and understood by all beginners, who construe it as uniform equanimity; but then when they let their minds go, the ordinary and the spiritual are divided as before, quietude and activity operate separately. So obviously this was only an intellectual understanding. - Foyan (1067–1120)

>People in older times asked questions on account of confusion, so they were seeking actual realization through their questioning; when they got a single saying or half a phrase, they would take it seriously and examine it until they penetrated it. They were not like people nowadays who pose questions at random and answer with whatever comes out of their mouths, making laughingstocks of themselves. - Foyan (1067–1120)
