The 3rd swapna that Mata Trishla saw was the lion.

Meaning:

In Jain tradition, this dream is considered highly auspicious. It indicates that the child to be born would be:

• very courageous
• powerful and fearless
• supreme among beings
• a destroyer of inner enemies like anger, pride, deceit, and greed

For Bhagwan Mahavir, this dream symbolized that he would be a महान आत्मा, spiritually powerful, and a great conqueror of karmas.
