Within the Tattvartha Sutra, the three jewels—right faith (samyag-darśana), right knowledge (samyag-jñāna), and right conduct (samyak-cāritra)—are presented as a single, integrated path to liberation. They are not three optional virtues but three inseparable dimensions of one spiritual orientation. Right faith provides the initial turning of the soul toward reality as taught by the Jinas: confidence in the true nature of the soul, karma, and liberation, and in the principles that structure existence. This faith is described as free from doubt and false belief, and it removes the deep-seated delusion that would otherwise distort every subsequent effort. Without such rectified vision, both knowledge and conduct are liable to be misdirected, however energetic they may appear.

Right knowledge then clarifies and articulates what right faith has already intuited. It is characterized as accurate, doubt-free understanding of the substances of reality and their modes, especially the tattvas that describe soul, non-soul, karmic bondage, and the path to release. This knowledge includes both scriptural learning and direct insight, so that doctrine is not merely held at second hand but becomes existentially meaningful. In this way, right knowledge specifies what is to be cultivated and what is to be abandoned, making it possible for conduct to be consciously aligned with the structure of reality rather than with habit or convention.

Right conduct is the practical outworking of right faith and right knowledge in the arena of daily life. It consists in behavior that accords with the insight gained: restraint, observance of vows, and the disciplined practice of nonviolence, truthfulness, non-stealing, celibacy or chastity, and non-attachment. Through such conduct, the influx of new karma is checked and the shedding of previously accumulated karma is supported, allowing the soul to be progressively purified. Conduct thus becomes the operative force that translates inner conviction and understanding into concrete transformation.

The Sutra portrays these three jewels as mutually reinforcing: faith orients, knowledge illuminates, and conduct actualizes. Faith without knowledge and conduct remains vague; knowledge without faith and conduct is merely theoretical; conduct without the other two lacks a clear foundation and direction. When cultivated together, they guide the aspirant through stages of spiritual purification, gradually loosening the bonds of karma and opening the way to complete liberation.
