In plain words
You throw away the stone and the skin. I did not say, 'Do not buy a mango.' Buy the mango fruit. Eat it. Take the essence. Throw away what is without essence; this is Vairāgya. Instead, if you tried to eat that stone too, saying, 'I myself paid money and bought it,' what foolishness that would be! That is why, if this Vairāgya does not examine the eternal and the transient and have the discrimination power of what must be taken and what must be thrown away, it turns into mere foolishness. To decide with that discrimination power what to take and what to throw away: that is Vairāgya.
So you must not take Vairāgya in a wrong sense. You must not think it means leaving everything and going to the forests. Experience divinity in everything. Keep divinity in view. That is true Vairāgya. It is not that we somehow leave wife and children, leave property and possessions, renounce every attachment and go off to the forest. Is the forest not the world as well? There, because there are no people, trees have grown. Here, because there are people, they are cutting the trees down. Apart from that, it too is a part of the world. So in the way we act, we must enquire into the good and the bad and try to experience it.
