There are many types of music and songs I won’t even discuss the higher music that Beethoven may have heard
The music that is very prevalent is the music in every country. Sung in Rap, rock and roll, etc and sung in movies. Everyone is crazy about them. The lyrics occasionally have meaning. May even make some intellectual sense. But yet they are not spiritual
There are two categories of spiritual music. Those that belong to the scripture and may have and give spiritual power
Then there is the spiritual songs written by Gyani. They are incredible. They give step by step information about the milestones in spiritual progress. They are abundantly present in GuJarati and Hindi. Possible in other Indian languages
Some of them guide. Those songs are called tattvagyana bhajan
kabirs songs are of That category
Also Omar Khayam
Also the quotes by Rumi.
However the bhajan by the Gyani are long. Can be several pages long. With instructions
Isn’t it sad that such a great heritage and no one is interested ?
