Answer

No. In Jain tradition, a śrāvaka cannot simply decide on his own and become a muni by self-declaration.

Explanation

Becoming a muni is not just a personal decision; it is a formal renunciation called dīkṣā. This normally requires:

• guidance from a qualified Ācārya or senior monk
• acceptance into the monastic order
• observance of the proper vows and disciplines

If no munis are currently available in a region, a śrāvaka may still develop strong vairāgya, live with great restraint, and prepare for renunciation. But he should not call himself a muni without proper initiation.

Spiritual Understanding

In Jain Dharma, discipline, humility, and proper order are very important. Even spiritual renunciation is not meant to be self-made or ego-driven. It is received with purity, guidance, and recognition from the tradition.

Takeaway

A śrāvaka may aspire to become a muni, but actual muni-dīkṣā must be taken through the proper Jain monastic process. Self-appointment is not the traditional way.
