Recently I heard this beautiful song sung by one of my absolute favourites Lata Mangeshkar from the movie Sadhi Mansa. The music of this song is composed by Anandghan and the lyrics are penned by Jagdeesh Khebudkar
In ऐरणीच्या देवा तुला ठिणगी ठिणगी वाहू दे, आभाळागत माया तुझी आम्हावरी राहू दे!, the word ऐरण refers to the anvil of the blacksmith and ठिणगी refers to the spark generated when a piece of metal placed on the anvil is struck with a hammer.
