Answer

It usually means the 363 philosophical views or doctrines discussed in Jain scriptural tradition, especially in connection with the Dṛṣṭivāda material. One traditional classification divides them into Kriyavāda (180), Akriyavāda (84), Ajñānavāda (67), and Vinayavāda (32). ( jainworld.jainworld.com)

Explanation

In Jain usage, sūtra means a concise scriptural teaching or precept. So “363 sutra mata” is best understood as 363 doctrines/views mentioned or refuted in that scriptural context, not as a separate ritual or prayer. ( encyclopediaofjainism.com)

Spiritual Understanding

The Jain purpose in discussing these views is to show that one-sided beliefs do not capture the full truth. This is closely related to anekāntavāda and syādvāda, which teach that reality must be understood from multiple perspectives. ( jainpedia.org)

Takeaway

So, in simple words, “363 sutra mata” means 363 philosophical doctrines/views in Jain tradition. ( jainworld.jainworld.com)
