The ratnatraya, the three jewels of Jainism, are right faith (samyak darshana), right knowledge (samyak jnana) and right conduct (samyak charitra). The Tattvartha Sutra opens by stating that these three together constitute the path to liberation, and the word "together" carries the weight of the doctrine: the tradition insists that none of the three is effective without the others. The standard analysis explains why. Faith without knowledge is blind; knowledge without faith lacks conviction and direction; and both without conduct leave the karmic influx unstopped, so that nothing changes.
Right faith is acceptance of the Jain account of reality, the categories, the nature of soul and non-soul, together with confidence in the teaching of the Jinas. It is treated as foundational in a technical sense, because knowledge counts as "right" knowledge only when accompanied by right faith; identical information held by someone with a false view is classified differently.
Right knowledge is correct and doubt-free understanding, and Jain epistemology classifies it into five kinds, ascending from ordinary sense-based and scriptural knowledge, through clairvoyance and knowledge of others' minds, to kevala jnana, omniscience.
Right conduct is the practice that stops influx and sheds what has accumulated. For mendicants this is the five great vows in their unqualified form; for laypeople it is the same five in limited form, together with supplementary vows and the tradition's graded ladder of eleven stages by which a householder may progressively approach the mendicant discipline.
The triad is deliberately parallel to, and quite distinct from, the Buddhist three jewels, Buddha, Dharma and Sangha, which are objects of refuge rather than components of a path. The Jain triad names three qualities of the practitioner. Jainism does have its own objects of veneration, and the Namokar Mantra salutes five categories of accomplished beings, but the ratnatraya describes what liberation requires rather than whom one honours.
What has been contested is the relative weight of the three. Strands emphasising rigorous ascetic conduct and strands emphasising right faith as itself the decisive turning have both existed, and the Digambara mystical tradition following Kundakunda gives an inward reading of all three, faith, knowledge and conduct as the soul's own self-directed states, which other Jain authorities have criticised as underplaying external observance. The argument is a familiar one in ascetic traditions and has not been settled.
