Inflib asked, “What is vatthu kama?”.
It means cravings to own material things that provide sense pleasures. “Vatthu” means basically “one’s property”.
For example, going to an art gallery and looking at famous paintings is not enough. One with vatthu kama for paintings would like to own such paintings.
When one gets to the Sakadagami stage, one would lose vatthu kama, but one still likes to enjoy sense pleasures. So, one may not desire to own paintings in the above case, but one still likes to look at them and enjoy them. That desire or craving is also lost when one gets to the Anagami stage.
You can apply it to anything that provide sense pleasure.
