Lesson: A pure heart is invincible
An arrogant king challenged a yogi:
"If you are truly enlightened, walk through this fire."
The yogi smiled and stepped into the flames—but he remained unharmed.
The king, shocked, asked:
"How did you do that?"
The yogi replied:
"Fire burns only what is impure. A soul free from karma and desires cannot be harmed."
The king fell at his feet and asked to be his disciple.
Moral: Purity of heart and mind makes one untouchable by suffering.
