I found this song in 2010 when I wanted to have a Ilaiyaraaja question in our Annual India Quiz organized by my club Indian Quizzing League. Raaja has composed the music for this bhajan written by Mahatma Gandhi
There is a special story on the bhajan. The bhajan was unearthed by Aditya Birla family in 2009 and it was written by Gandhi when he stayed in their house.
