In Jainism (especially in the Śvetāmbara tradition), the Agam scriptures are grouped mainly as:

1. Angas (Aṅga Āgamas)

• Meaning: “Aṅga” = limb. These are the main “limbs” of Bhagwan Mahavir’s teachings.
• Status: They are considered the primary canonical texts in the Śvetāmbara tradition.
• Number (Śvetāmbara): Traditionally 11 Angas are accepted.
• Content (in simple terms):

- Teach right conduct for monks and nuns. - Explain Jain philosophy (soul, karma, bondage, liberation). - Contain questions–answers between Ganadharas and Mahavir. - Include stories that teach morals and Jain principles.

2. Upangas (Upāṅga Āgamas)

• Meaning: “Upāṅga” = subsidiary / secondary limb.
• Status: Texts that support and explain the Angas.
• Number (Śvetāmbara): Traditionally 12 Upangas.
• Content (broadly):

- Detailed explanations of topics already found in Angas. - Descriptions of Jain cosmology (lok, heavens, hells, etc.). - Stories of great śrāvaks, kings, monks, and their spiritual progress. - Teachings on vows, penances, right behaviour for laypeople and ascetics.

3. “Parikramas” (actually Prakirnaka / Prakīrṇaka Sūtras)

In the list of Agams, the third related group is usually called Prakīrṇaka Sūtras, not “Parikramas”, so most likely you are referring to these.

• Meaning: Prakīrṇaka = miscellaneous / separate pieces.
• Status: Short, independent texts focused on specific practical topics.
• Number (Śvetāmbara): Traditionally 10 Prakīrṇaka Sūtras.
• Content (in simple terms):

- Short texts on: - Daily practices like sāmāyik, pratikraman, pratyākhyān. - Devotional stutis and praise of Arihants and Siddhas. - Rules and guidance for pure conduct in specific situations. - They are more practical and focused, helpful for day‑to‑day spiritual discipline.

Difference in Śvetāmbara and Digambar view

• Śvetāmbara:

- Accept a canon of 45 Agams, grouped as: - 11 Anga - 12 Upanga - 6 Cheda Sūtras - 4 Mūla Sūtras - 10 Prakīrṇaka Sūtras - (and sometimes Nandi & Anuyogadvāra noted separately)

• Digambar:

- Believe that the original Angas were lost long ago. - Do not accept the present Śvetāmbara Agams as authentic. - Follow other main texts (like Ṣaṭkhaṇḍāgama, Kaṣāyapāhuḍa, etc.), so the Anga–Upanga–Prakirnaka classification is mainly a Śvetāmbara Agam framework.
