Answer

In Jain Dharma, the word is usually Āgama books (scriptures), not “Yagami books.”

The key Āgama scriptures differ in Śvetāmbara and Digambara traditions:

• Śvetāmbara tradition: accepts a preserved canon of Jain Āgamas.
• Digambara tradition: holds that the original Āgamas were gradually lost, and therefore does not accept the Śvetāmbara Āgama canon as the original complete scripture.

Śvetāmbara Āgama Books

Śvetāmbara Jains traditionally classify their Āgamas into groups such as:

• 11 Aṅgas
• 12 Upāṅgas
• 10 Prakīrṇakas
• 6 Cheda-sūtras
• 4 Mūla-sūtras
• 2 Cūlikā-sūtras

Important Śvetāmbara Āgamas include:

• Ācārāṅga Sūtra
• Sūtrakṛtāṅga Sūtra
• Sthānāṅga Sūtra
• Samavāyāṅga Sūtra
• Bhagavatī Sūtra / Vyākhyāprajñapti
• Jñātādharmakathā
• Upāsakadaśāḥ
• Antakṛddaśāḥ
• Anuttaraupapātikadaśāḥ
• Praśnavyākaraṇa
• Vipāka Sūtra

Traditionally, there were 12 Aṅgas, but the 12th, Dṛṣṭivāda, is considered lost.

Digambara Scriptures

Digambara tradition teaches that the original Āgamas were lost over time. Therefore, Digambara Jains give special importance to later authoritative works based on the teachings of the Jinas.

Key Digambara scriptures include:

• Ṣaṭkhaṇḍāgama
• Kaṣāyapāhuda
• Samayasāra by Āchārya Kundakunda
• Pravacanasāra by Āchārya Kundakunda
• Niyamasāra by Āchārya Kundakunda
• Pañcāstikāya by Āchārya Kundakunda
• Tattvārtha Sūtra by Āchārya Umāsvāti / Umāsvāmi
• Ratnakaraṇḍa Śrāvakācāra by Āchārya Samantabhadra
• Āptamīmāṃsā by Āchārya Samantabhadra
• Gommaṭasāra by Āchārya Nemichandra Siddhānta Chakravartī

Explanation

The difference is mainly about the preservation of the original teachings:

• Śvetāmbara view: many original Āgamas were preserved and compiled through tradition.
• Digambara view: the original Āgamas were lost, so later authentic texts preserve Jain doctrine and practice.

Both traditions deeply revere the teachings of the Tīrthaṅkaras, but they differ on which scriptural collections are accepted as canonical.

Takeaway

The key point is:

• Śvetāmbara: accepts the Āgama canon.
• Digambara: does not accept the Śvetāmbara Āgamas as original canon and relies on respected Digambara scriptures such as Ṣaṭkhaṇḍāgama, Kaṣāyapāhuda, and works of great Āchāryas like Kundakunda.
