Why Krishna love His flute
Krishna’s flute is the symbol of Freedom or Pranava. The sound of this divine flute thrilled the heart with delight and instilled new life and joy. It produced God-intoxication in all beings and infused life even in insentient objects. The sweetness of the music was unsurpassed. He who heard once the music of Krishna’s flute cared not for the nectar of heaven or the bliss of Moksha. Krishna has preached Prem (love) through His flute.
Once Radha asked Krishna:
"O my dear! Why do You love the flute more than me? What virtuous actions has it done so that it can remain in close contact with Your lips? Kindly explain to me, my Lord, the secret of this. I am eager to hear".
Shri Krishna said:
"This flute is very dear to Me. It has got some wonderful virtue. It has emptied off its egoism before I began to play. It has made its inner hollow quite void and I can bring out any kind of tune, Raga or Ragini, to My pleasure and sweet will. If you also behave towards Me in exactly the same manner as this flute, if you remove your egoism completely and make perfect self-surrender, then I shall also love you in the same manner as I love this flute".
This body also is the flute of Lord Krishna in the macrocosm. If you can destroy your egoism and make total self-surrender, unreserved Atma-Nivedan to the Lord, He will play on this body-flute nicely and bring out melodious tunes. Your will will become merged in His Will. He will work unhampered through your instruments, body, mind and Indriyas. You can rest very peacefully then without cares, worries and anxieties. You can watch the play of the universe as a Sakshi. Then your Sadhana (devotional service) will go on by leaps and bounds, because the Divine Will or Divine Grace itself will work through you. You need not do any Sadhana at all.
