I think you might be referring to a Jain topic that starts with “mr.” If you meant Moksha (liberation), I can explain it simply:

• What it is: Moksha is the ultimate goal in Jainism—the release of the soul (jiva) from the cycle of birth and death (samsara). When a soul attains Moksha, it is free from all karmic bonds and experiences ineffable bliss.
• How it happens: A soul accumulates karma through thoughts, words, and actions. Through right conduct, right knowledge, and right faith (the threefold path), along with earnest purification and detachment, karma is shed. In Jainism, this process is usually described in terms of practicing the five vows (non-violence, truth, non-stealing, celibacy, and non-possessiveness) with intense inner discipline.
• The end result: Once all karmic bonds are burnt up, the soul remains in its pure, infinite nature, free from any physical body, and experiences timeless, pure bliss.
• Digambar vs. Shvetambar nuances (very brief): Both traditions affirm liberation as the goal, but they differ in certain details about the path, the role of monastic vows, and the interpretation of certain scriptures. In general, Digambar monks emphasize severe asceticism and the idea of complete renunciation, while Shvetambar communities emphasize a broader inclusive practice with both monks and nuns following recognized vows.

If you meant something else by “mr,” please tell me the exact term you have in mind (for example, a specific sutra, mantra, or concept), and I’ll explain it in Jainism with the authentic meaning and nuances.
