[Kalobbis]

"If, Aananda, there were no kamma ripening in the fine-material realm, would fine-material becoming be discerned?"

Fine-material realm is delighting in materiality, such as delighting in material possessions such as money, property, etc.

Fine-material realm is also delighting in the material jhanas (1st, 2nd, 3rd and 4th), which have their foundation in the calming of the physical body.

There are three kinds of becoming: sensual, material and immaterial.

How strange is Bhikkhu Bodhi to regard these are something concrete?

Which beings spend 100% of their time and life engaging in the sensual realm?

This would imply sensual pleasure could be sustained permanently.
