Answer

Jamali argued with Bhagwan Mahaveer mainly because of a doctrinal disagreement and growing ego. He was unable to accept Mahaveer’s teaching about how an action or object becomes truly complete only when all parts are finished.

Explanation

According to Jain tradition, Jamali once misunderstood Mahaveer’s teaching and insisted that something should be called “done” as soon as the process begins or appears complete to him.

Mahaveer taught a more precise view:

• A thing is not fully complete until every required part is finished.
• Partial completion should not be mistaken for final completion.

This disagreement became a major debate. Over time, Jamali separated from Mahaveer’s path and became known as one of the early schismatics in Jain history.

Spiritual Understanding

In Jain Dharma, this story teaches:

• Humility is essential — ego can turn a small misunderstanding into a serious conflict.
• Right understanding matters — even a subtle wrong view can lead one away from truth.
• Respect for the Tirthankar’s teaching is central to spiritual progress.

Takeaway

Jamali’s argument was not just about words; it was about misunderstanding truth through ego and attachment to one’s own view. Jainism teaches us to stay humble, listen carefully, and seek correct understanding.
