For you the best tapas will be to devote yourselves to kirtan or hymn singing and katha or exposition of the sacred word both performed in the sangat, i.e. holy assembly. This will bring you and your listeners solace and enhance your faith.” Bhai Malo and Bhai Manga dedicated the rest of their lives to katha and kirtan.
