What is the Story of king pari who gave chariot to the plant?

The story goes that one day as Pari was going through a forest on his golden chariot, he felt the desire to quench his thirst and so stopped near a stream. When he returned he found that a mullai plant (a wild jasmine creeper) had entwined itself around one of the wheels of the chariot. To move the chariot would mean to break the tendril. Sometimes it just takes a trigger to bring on enlightenment, and to Pari it came at that moment in time. So he actually gave his golden chariot to the plant, and he walked back to his palace. Henceforth he gave away all his riches. He became known for his love for nature and his philanthropy (he was one of the seven Tamil kings known for nature conservation).

Tamils are well known for their hospitality.It is emphasized every now and then.

The above King's gesture to an ordinary Jasmine plant a nice example.
