Dada Bhagwan said this quote
“ There are two types of knowledge. One is about what is right and wrong, what is helpful and harmful in this world, and the second is about the path to final Liberation (Moksha). The one who attains the knowledge about Moksha will indeed get the knowledge about what is helpful and harmful in the world. Or else, there should be saints around who know about what is helpful and harmful in this world. ”
