Jainism is an eternal dharma (way of spiritual truth) that guides a soul to liberation (moksha) by following a practical path of ethics, knowledge, and faith. Its core principles are:

• Ahimsa: non-violence and non-harm to all living beings
• Anekantavada: many-sidedness of truth; reality is complex and can be understood from multiple viewpoints
• Aparigraha: non-attachment to possessions and desires
• Ratnatraya (the three jewels): Samyak Darshana (right faith), Samyak Jnana (right knowledge), and Samyak Charitra (right conduct)

In Jain practice, liberation comes through purifying karma by living with right faith, right knowledge, and right conduct, often summarized as following the Five Vows and other ethical disciplines.

Two quick notes on traditions:

• Digambara and Śvētāmbara traditions share the same basic aims and core principles but differ in some canonical texts, beliefs about the Tirthankaras, and practices. For example, Śvētāmbara tradition accepts a broader canon and traditional text lineage, while Digambara emphasizes renunciation and monastic discipline in specific ways.
• Both agree on the triple path of Faith, Knowledge, and Conduct as central to the Jain path.
