 In an Early Buddhist Texts (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.The Buddha considered Upāsaka Citta to be the most learned and lucid of all the lay Dhamma teachers.
