In plain words
The moment it has become hollow, Kṛṣṇa calls ‘hello’. Then He takes it up and plays it. His fingers touch each hole. The flute is on His lips. God's breath, in and out, passes through that flute, makes many hear that sound, and plunges them in Ānanda. We must make ourselves into the two things God needs. One, sandals; the second, the flute. Which of these do I want? As for sandals, they must carry your whole weight upon them. They must bear everything for the feet: the stones, the thorns and the rubbish beneath. It is the sandals that have to bear every hardship. This is a great hardship. Who knows how it would be! But to become a flute is very easy. If you have to hold this towel like this, your hand starts to ache. So holding the towel tight is no great thing. Letting go is very easy. So greatness does not lie in our holding desires tight and suffering hardships. Letting go itself is very easy. That is Vairāgya. We must attain that Vairāgya as far as we can. But while we are in this world, attaining that Vairāgya is not so easy. My son, my child, my wife, my mother: what is this ‘my, my’? In these very words it shows that it is not yours. My son: is he mine? The son is not mine. My mother: the mother is not mine. If you learn the meaning of this ‘my’, you will understand it fully. You must learn the meaning of ‘my’. Not ‘mine’. My house: the house is not mine. So, first of all, you must give up the feeling ‘mine, mine’. This very thing Vedānta has called ‘neti neti’. Neti does not mean the ghee made by melting butter. ‘Neti’ means ‘na + iti’. Have the faith that all this is nothing but the form of God.
