That’s a good point. “Anatta” refers to a characteristic of nature: Worldly things (and any perceived pleasures) are devoid of any substance (unfruitful) and have dangerous consequences for the future.
- Also, “sukha” is not a feeling (vedana). It is the complete absence of suffering.
- The post “Nibbāna “Exists”, but Not in This World” explains it: “Nibbāna sukha” is NOT a feeling. It is the absence of suffering. The closest analogy is the following: Suppose someone has had a chronic headache from birth. One day, it is cured, and he feels a great relief. That relief was not a new vedanā but the absence of “dukkha vedanā.”
