In English
No spiritual study or sadhana can help to purify one's heart unless one makes the effort himself. And when the heart is purified, it becomes a worthy abode for the Divine. Whatever you do you must regard it as a duty done without any motive of self-interest or selfish gain. It is only when all actions- whether they be or or or any kind of sadhana - are done as offerings to the Divine, will they become sanctified and liberating. Through (desire filled actions) we take birth, through (desireless actions) we can attain freedom from re-birth.
