The diminutive singer -- a Delhiite who came to Mumbai in search of career and fortune and lived in the Andheri railway station during his struggling days -- has taken the industry by storm with a slew of hits both as a playback singer and as an album artiste.
Kher, whose Sufi songs have made him instantly recognisable, says the names of his two albums say it all - "Kailasa" and "Kailasa Jhoomo Re".
"'Kailasa' means heaven and I experience heavenly bliss through my songs. I feel the music within myself," Kher told.
The current singing sensation of Bollywood shot to fame with back-to-back hits "Allah Ke Bande" from "Waisa Bhi Hota Hai II" and "O Sikander" from "Corporate".
His story is the stuff of folklore, the classic rags to riches story, beginning from the railway station and moving on to the air-conditioned studios of the big and powerful.
He fought for every inch of space he now enjoys in the Indian music industry, and is now called the 'fragrance of rural Indian soil'.
Kher has produced some of the biggest musical hits of recent time, like "Teri Deewani" from "Kailasa", "Chak De Phatte" from the hit 2006 film "Khosla Ka Ghosla". Songs from his second album "Kailasa Jhoomo Re" are on high rotation on radio stations and television channels.
The popular but humble singer says he is not consciously trying to lie low in an industry in which a newcomer grabbing the limelight can cause some flutter among the biggies.
"I'm naturally like this," he said. "I'm like the river that keeps on flowing without worrying whether the banks are clean or dirty. I love staying with my music. That's my nature."
The versatile Kher, who also does a lot of international stage shows, adds that Indian music is slowly gaining global recognition.
"Today there is a lot of exposure for Indian singers. The world is becoming a global village and I can see more and more people appreciating our music."
