In Jain Dharma, no large scripture collection is accepted in exactly the same way by every sect and subsect.

The one text most widely accepted across all major Jain traditions is:

• Tattvartha Sutra by Acharya Umasvami / Umasvati

It is respected by both:

• Digambar
• Shwetambar

and is generally treated as an authoritative summary of Jain philosophy.

Important clarification

• Shwetambar traditions especially accept the Agamas as scriptures.
• Digambar traditions do not accept the same Agama canon in the same form.
• So, the Agamas are not universally accepted by all Jain sects.

Short answer

Tattvartha Sutra

If you want, I can also list:

1. the texts accepted by Digambar only,
2. the texts accepted by Shwetambar only, and
3. the common philosophical texts revered across Jain traditions.
