In plain words
Only when the feeling of “mine”, “mine” is given up does it dawn that nothing is “mine”. That does not mean to give up everything; Vidyā taught that ‘to enjoy with a spirit of sacrifice is one's duty.’ Vidyā also commands that the touchstone of holy and meritorious karmas is ‘sacrifice’, and the touchstone of unholy and sinful karmas is ‘greed’. Wish to live a hundred years doing the work that is to be done; there is nothing wrong in that. Vidyā also teaches, ‘Do the work you do knowing what it is.’
