Though you may have attained freedom from being obstructed by anything you encounter and managed to reach the emptiness of words, phrases, and all entities—the realization that mountains, rivers, and the earth are but concepts, and that concepts cannot be grasped either—and [even if] you are equipped with so-called samadhi and the ‘sea of [original] nature’: it still is nothing but waves churning round and round without any wind. Even if you forget [dualistic] knowledge in awakening—awakening is nothing other than buddha-nature—and are called ‘a man without concern,’ you still must realize that everything hinges on a single thing: going beyond!
