‘Although “nirvana”, “tathagata”, and “the diamond prajna-paramita” are different names, they are all uncreated dharmas. Created dharmas are the dharmas of the world. Uncreated dharmas are the dharmas that transcend the world. Often, people who cultivate think that uncreated dharmas refer to emptiness or stillness, and they turn their minds and bodies into ashes and deadwood and think they are practicing Buddhism. But all they are doing is trying to catch the wind or kick a shadow. They are lost and deluded people.’ (Commentary on the Diamond Sutra)
