Answer

In Jain tradition, “Jain councils” are usually understood as vācanās — formal recitation and preservation sessions of the sacred teachings. Their main purpose was to protect Jain knowledge when oral transmission was in danger because of famine, migration, and the loss of learned monks. The exact dates are not fully certain, and different Jain traditions preserve different accounts. ( jainpedia.org)

Explanation

The most important councils are usually described as follows:

• Pāṭaliputra: This is the earliest major recitation. Śvetāmbara tradition associates it with Sthūlabhadra, while Bhadrabāhu is connected with the older scriptural memory, especially the Pūrvas. It is traditionally placed around 160 years after Mahāvīra’s nirvāṇa, though historical dating is uncertain. ( jainpedia.org)
• Mathurā: A later recitation was held under Skandila. Jainpedia notes this as part of the Śvetāmbara effort to preserve the texts after earlier losses. ( jainpedia.org)
• Valabhī: This is the most famous council in Śvetāmbara history. It is associated with Devarddhi-gaṇi Kṣamāśramaṇa, who supervised the final writing down of the Śvetāmbara canon in the 5th century CE. Traditional dates vary, but Jain sources commonly place it around 453 or 466 CE. ( jainpedia.org)

The broad storyline is that, after a great crisis, Jain monks gathered what was still remembered and wrote it down so that the teaching would not disappear. According to Śvetāmbara tradition, the Valabhī council became the final redaction of the canon. ( jainpedia.org)

Spiritual Understanding

The councils are important because they show a deeply Jain concern: preserving right knowledge with care, discipline, and collective responsibility. In Jain Dharma, scripture is not treated casually; it is something to be protected with humility and reverence. The councils reflect that attitude of safeguarding śruta-jñāna for future generations. ( jainpedia.org)

They also show how the Jain community responded to hardship without abandoning the Dharma. Instead of letting sacred learning vanish, the monks made a disciplined effort to recite, verify, and preserve it. ( jainpedia.org)

Important Sect Difference

A key point is that Digambara and Śvetāmbara traditions do not view these councils the same way. Śvetāmbara tradition accepts the councils as important steps in preserving the Āgamas. Digambara tradition does not accept the Śvetāmbara canon in the same way and holds that the original Āgamas were largely lost; it gives authority instead to texts such as the Ṣaṭkhaṇḍāgama and Kaṣāya-prābhṛta.

Takeaway

If you want the simplest summary:

Jain councils were preservation meetings for sacred knowledge. Their purpose was to protect the teachings of Mahāvīra and the earlier Jinas, especially during times of crisis. The most famous councils are Pāṭaliputra, Mathurā, and Valabhī, with Valabhī being the final major recitation in Śvetāmbara tradition. ( jainpedia.org)
