Dharmopadesha is the teaching or instruction of dharma (righteous conduct) that accompanies swadhyaya (self-study) in Jain practice.

• In swadhyaya, a Jain pursues not only study of scriptures but also the internalization of right faith, right knowledge, and right conduct. Dharmopadesha is the guidance that helps a practitioner apply that study to daily life, purify conduct, and progress on the path to liberation.
• It reflects the Jain aim to transform understanding into ethical action: what to believe, what to know, and how to live rightly according to Jain principles.
• There is no essential difference in this concept between Digambar and Śvētāmbar traditions—the core idea is the same: swadhyaya plus dharmopadesha leads to purer conduct and spiritual progress.
