Amruthavarshini

'Amruthavarshini' raaga is a pradhi madyama raaga known to bring rain to earth.
There have been numerous occasions where musicians would gather in a temple singing various kritis all in this ragam, and invariable a few days later there would be rain. Pretty interesting right ?
In fact there is also another incident in Ramayana when Ravana set fire to Hanuman’s tail, he set fire to the entire Lanka. How was the fire put out? Legend has it that Ravana played the Amruthavarshini raga on his Veena and brought forth rain.
