How to explain the concept of "body" as in "rupakaya" in intuitive terms?

I am looking at [Rupakaya on the Rigpa Wiki](https://www.rigpawiki.org/index.php?title=Rupakaya) , and it says: > [It] refers to the two 'form kayas' of a buddha: nirmanakaya and sambhogakaya. It is said that the rupakaya arises from the accumulation of merit and the dharmakaya from the accumulation of wisdom. Using the term "body" confuses me, like the [Dharmakaya](https://www.rigpawiki.org/index.php?title=Dharmakaya) , the "Absolute or Truth Body". How can truth have a body? Can you explain how this works in an intuitive way?
