Which of the following is one of the 'three gems' (triratna) of Jainism ?

The 'Three Gems' (Triratna) of Jainism are Samyag-darshana (Right Faith/Vision), Samyag-jnana (Right Knowledge), and Samyag-charitra (Right Conduct). These constitute the path to liberation (moksha) in Jain philosophy. Brahmacharya (celibacy) and Asteya (non-stealing) are among the five vows (Pancha Mahavrata) of Jain ascetic practice, but they are not the Triratna. Sunrita refers to truthful and pleasant speech.
