Citta

Citta (Sanskrit: Citra) was one of the chief lay disciples of the Buddha.He was a wealthy merchant from Savatthi. His life and character were so pure that near his death, had he wished to be a chakravartin, it would've been granted. However, he turned down this wish as it was temporal. He became a saint that became a non-returner.

In an early sutta (SN IV.297-300), Citta is asked by Nigantha Nataputta (Mahavira) if he believes the Buddha who says that there is a concentration free from deliberation and thought. He initially gives an ambiguous answer, but then turns out not to believe, but to know these things from his own experience obtained while practicing the jhanas.
