Finance is essential as without that living is impossible. However, greed leads to additional strain on the body and mind and ultimately to high blood pressure etc.
Environment – when we need more,
Water, we dig more borewells and use the sub-soil reserve.
Food, we add chemicals which lead to new diseases,
After realization greed gives place to contentment and peace.
