Hi Pudgala

Of 'beings' ('satta'), on the level of ultimate reality, the Theravada scriptures appear to share your point of view:

Ven. Radha went to the Blessed One and, on arrival, having bowed down to him, sat to one side.

As he was sitting there, he said to the Blessed One:

"'A being,' lord. 'A being,' it's said. To what extent is one said to be 'a being'?"

Satto, satto’ti, bhante, vuccati. Kittāvatā nu kho, bhante , sattoti vuccatī’’ti?

"Any desire, passion, delight or craving for form, Radha: when one is caught up there, tied up there, one is said to be 'a being.'

"Any desire, passion, delight or craving for feeling... perception... fabrications...

"Any desire, passion, delight or craving for consciousness, Radha: when one is caught up there, tied up there, one is said to be 'a being.'
