Miseries and misfortunes are diseases stored in the fold of destiny, precisely in mind, and must appear in time, sooner or later, in this life or in any subsequent life. Man very commonly mistakes material prosperity for peace and is often overwhelmed by the rude shocks from grief. But sufferance is a process of inner cleansing and to get immunity from the diseased destiny. Destiny of decay, death and bereavements are natural in a life. But it is possible to act for liberation from the bondage of births and rebirths and the consequent sufferances and complete cessation of all pains of life. Purusakara by cultivation of cittasuddhi (চিত্তশুদ্ধি) or subha karma (শুভকর্ম) or vidya (শুদ্ধবিদ্যা ) have attributes of fire in them to burn the impurities in mind that originate from ignorance (অপবিদ্যা / অজ্ঞানতা) and to give the life immunity from sufferings.
