“Nothing whatsoever should be grasped at or clung to.”
Buddha, when asked whether his entire teaching could be summarized in a single sentence, said this: “Nothing whatsoever should be grasped at or clung to.”
The reason a person’s mind is distracted and unable to concentrate is that the person is grasping at and clinging to something. The reason a person lacks insight is the same. When the person is finally able to practise non-grasping, then simultaneously he attains the Noble Paths, their Fruits, and ultimately nibbbana (Sanskrit, nirvana). Buddha was a man who grasped at absolutely nothing. The Dhamma teaches the practice and the fruit of the practice of non- grasping.
