Attachment is predominant in mankind. Some see joy in money, some see only grief in money, some see it in licentiousness and some see it in sacrifice. Therefore no one can draw a line where it can be otherwise simply because it is always a subjective issue in everyone’s view and that too how he looks at the issues!
Likewise there cannot be any definition of a sin, lust, happiness etc. as we neither do it for virtue nor we do it for sin. We only do what we are made to do at a point of time by happenings around us. A very interesting and engrossing philosophical & mind boggling fiction on the changing relations of a woman–saint–a lover to seek what is the ultimate happiness?
