Tirthankar Parishtapanika Samiti is one of the five "Samitis" (disciplines) observed in Jain codes of conduct. It specifically means the careful handling of disposal or throwing away of things so that no living beings are harmed.

• What it means (arth): When you throw away waste, trash, or excreta, you do so with great care to avoid injuring any insects or small beings. The idea is to minimize harm to all living creatures in everyday actions. This is taught as a practical ethical guideline for both monks and householders.

• Where it fits in Jain practice: Parishtapanika Samiti is paired with other samitis (like Adan-nikshepana Samiti for receiving/keeping things, Bhasha Samiti for speech) as part of a broader code of conduct that trains the mind, speech, and body to be gentle and non-harmful in daily life.

• Digambar vs. Shwetambar note: The basic principle of careful disposal is shared across Jain traditions, but details and emphasis can vary slightly by sub-tradition (e.g., different monastic codes or practical rulings within Digambar and Śvetāmbara lineages). The core idea remains—dispose with compassion and non-violence, so as not to harm small beings.

If you’d like, I can give the concise Purāṇic wording or a short explanation from Digambar and Śvetāmbara perspectives.
