“Buy one – get one free” may be a marketing gimmick. But it is true in real life in many ways.
We buy (i.e. harboring this emotion) anger and get acidity free. We buy jealousy and get headache free. We buy hatred and get ulcer free. We buy stress and get blood pressure free and so on.
Conversely, if we buy trust, we get friendship free. If we buy exercise, we get health free. If we buy peace, we get prosperity free. If we buy honesty, we get sleep free. If we buy Dharma, we get all good virtues free.
May God bless us with the wisdom to buy right things for a healthy and purposeful life!
