Here is a simple, structured summary focused on Kartavya (duties) as described in Shwetambar Jain texts, with note on time or timing where relevant.

1) What Kartavya means in Shwetambar texts

• Core idea: Kartavya refers to obligatory duties or moral obligations that a Jain adherent should perform to progress on the path of Non-violence (ahimsa) and spiritual purification.
• Emphasis: Duties are framed to cultivate self-discipline, truth, restraint, compassion, and detachment from worldly attachments.

2) Major categories of Kartavya in Shwetambar literature

• Personal conduct (Swadharma)

- Observance of ahimsa (non-violence) in thought, speech, and action. - Satya (truthfulness) balanced with compassion and non-harm. - Brahmacharya (celibacy or sexual restraint) and restraint of indulgence. - Tap (austerity) and self-discipline in daily life.

• Religious duties (Dharma-specific practices)

- Puja, meditation, and reflection to develop right conduct and right faith. - Samayik (period of concentrated meditation and equanimity), often practiced daily within a defined time frame. - Pratikraman (ritual of reflection and remorse) to review misdeeds and renew vows. - Nijā/Niyam (observance of personal vows and rules) appropriate to one’s stage of life (śrāvikā/śrāvaka, monk/nun, etc.).

• Communal and ethical duties

- Dana (charity) and service, helping others while maintaining non-violence. - Aparigraha (non-attachment) and reduced possessions, with mindful restraint on desires. - Respect for teachers and elders, upholding communal harmony and Jain ethics.

• Monastic duties (for śrāvakas/śrāvikās who take on more rigorous vows)

- Strict adherence to discipline, renunciation of worldly ties, and further refinement of conduct and knowledge. - Regular study of scriptures, philosophical inquiry, and teaching of Jain principles.

3) Time-related aspects of Kartavya

• Daily duties

- Many Shwetambar practices prescribe a daily rhythm of duties, including morning and evening routines, Samayik periods, meditation, and adhering to ahimsa in daily actions.

• Timed rituals and practices

- Samayik and Pratikraman are typically performed within specific time windows or daily schedules, emphasizing consistency and regular self-purification.

• Periodic and seasonal duties

- Ekadashi or other fasting days, seasonal fasts, and extended periods of contemplation or study may be part of one’s kartavya, depending on local tradition and guidance from preceptors.

• Life-stage adjustments

- The exact scope of kartavya can vary by whether one is a lay follower (upāsak/upāsik) or a renunciate (śramaṇi/śramaṇī). Monastic duties impose stricter timing and cadence, while householders adapt duties to family life and work.

4) How to apply these kartavya in practice (simple guidance)

• Start with core universal duties: non-violence, truthfulness with compassion, and restraint.
• Establish a daily routine that includes a dedicated period for Samayik and Pratikraman.
• Practice Aparigraha by regularly assessing possessions and desires; adopt mindful consumption.
• Engage in charitable acts and service to others, small and large, as a practical expression of karta-vya.
• Study Jain scriptures or guidance from trusted Shwetambar tradition teachers to align daily actions with tradition-specific interpretations.

If you’d like, I can tailor the summary to a specific Shwetambar text or author (for example, a particular sutra, stotra, or doctrinal work) and provide exact phrasing and an analysis of the time-related aspects as described there.
