Dada Bhagwan said this quote

There is no means other than vitrag-science (science that frees us from all attachments) that will give Final-Liberation [Moksha]. Other means [methods, instruments] will cause bondage; they only help to pass the time; [whereas] means to attain the Eternal Thing (experience of Pure Soul) can be attained from the ‘Gnani Purush’ (the enlightened one).
