Zen Wisdom 56

These four views are common attachments for ordinary sentient beings, whether they are practitioners or not. People want to believe in immortality, in an unchanging self that will continue through eternity, either in some form of heaven, or in another life. They believe that such a state will be eternally blissful, but they are defining bliss from their own experience, which is one of attachment. They believe that this state, where an unchanging self enjoys the bliss of eternal life, will be one of purity ─ no more suffering or defilement. However, when people speak of purity or impurity, it is usually from the perspective of physical enjoyment in the realm of desire.

Most people, including serious practitioners, cling to these four inverted views. People with such attachments have not truly seen into their self-nature. It is a fundamental Mahayana principle that nothing is permanent or absolute. There is no unchanging self, there is no absolute bliss or purity. This is stated very clearly in the Heart Sutra and in the Diamond Sutra. There are no distinctions between eternity and impermanence, self and others, happiness and suffering, purity and impurity. If, in your practice, there is still attachment to any of these inverted views, then you have not truly experienced kensho, at least not deep kensho.
