Arth (meaning)

• Jain agamas and tradition describe 8.4 million types of living beings (jīva-yoni).
• In this sutra we remember those categories (earth-bodied, water-bodied, fire-bodied, air-bodied, one-sensed plants—two kinds, two-/three-/four-sensed beings, heavenly beings, hell beings, five-sensed animals, and humans).
• Then, with humility, we seek forgiveness for any harm we have done, caused others to do, or approved of—by mind, speech, or body—toward any of these beings. “Micchhā mi dukkadam” means “May my faults be fruitless; I ask forgiveness.”

Tradition note

• This sutra is widely recited in Śvetāmbara pratikraman during kṣamāpanā (asking forgiveness). Digambara tradition also accepts the doctrine of 8.4 million life-classes; wording and usage may vary by paddhati (ritual manual). It is a devotional/ritual recitation, not an Āgama-verse.
