In Jain tradition, Rajul/ Rajimati was not the reason Neminath dada took the wedding procession. The key point is this:

• Neminath dada had agreed to the marriage arrangement
• While going for the wedding, he saw animals kept for slaughter for the marriage feast
• Out of deep compassion and ahimsa, he immediately renounced worldly life

So the story teaches that even a royal wedding should not involve violence.

About “three rath”, in many tellings this refers to the royal wedding procession / arrangements of that time. It does not mean Neminath approved of violence or marriage for worldly enjoyment. His renunciation happened before the marriage was completed.

Also, Rajul was not shown as non-veg in the Jain story. The focus is on the violence connected with the feast and royal ceremony, which inspired Neminath dada’s vairagya.

In short:

• Neminath dada did not renounce because of Rajul
• He renounced because of complete compassion for जीव-हिंसा
• The story is a strong Jain lesson on ahimsa and vairagya

If you want, I can also explain the full Jain story of Neminath and Rajimati in simple language.
