Premanand Maharaj Ji
How can I stop being greedy for more and more money?
Contentment ends greed for money
Until there is contentment, the craving for wealth never settles, however much comes. Naam jap, worship and company of sadhus (holy people) purify the intellect.
Until there is contentment, the desire for wealth does not calm down. However much you get, it will keep growing.
