Dada Bhagwan said this quote
“ Why is there inner burning [antar daah, inner suffering] present? Inner Burning [Antardaah] is not dependent/based on merit or demerit karma (paap-punya). Inner Burning [Inner suffering] is indeed present in both suffering producing karmas, unpleasant (ashata vedaniya) as well as pleasant (shata vedaniya). Inner Burning [Inner suffering] is dependent upon the wrong belief. ”
