Though certain recluses and brahmans claim to propound the full understanding of all kinds of clinging... they describe the full understanding of clinging to sensual pleasures and clinging to views without describing the full understanding of clinging to rules and observances and clinging to a doctrine of self. Why is that? They do not understand two instances... therefore they describe only the full understanding of clinging to sensual pleasures and clinging to views without describing the full understanding of clinging to rules and observances and clinging to a doctrine of self.
