In Jainism, there isn’t a single universal “mantra” that describes how to acquire knowledge. Instead, the path is defined by a trio of practices and the triple jewels of correct view, knowledge, and conduct.

What helps you acquire knowledge (arth and practice):

• Shravan (श्रवण): Listening to the authentic Jain scriptures and learned teachers. This is the first step to receive reliable information.
• Manan (मनन): Reflecting and analyzing what you have heard to understand it correctly.
• Nidhidhyasana (निधिध्यास): Deep contemplation and meditative absorption to internalize and assimilate the knowledge.
• Threefold path of right view, right knowledge, and right conduct:

- Samyak Darshan (सम्यक दर्शन): Right faith or correct understanding. - Samyak Jnana (सम्यक ज्ञान): Right knowledge. - Samyak Charitra (सम्यक चारित्र): Right conduct.

• These together lead to kevala jnana (केवलज्ञान), the ultimate, omniscient knowledge, beyond ignorance.

Notes:

• Digambar and Shwetambar traditions may present nuances in terminology or emphasis, but the core method—shravan, manan, nididhyasana—and the aim of attaining pure knowledge remain central.
• If you want, I can provide short verses or sutra quotes from Jain scriptures that illustrate these practices (and indicate how they are treated in Digambar vs. Shwetambar contexts).
