Among Krsna's innumerable pastimes, however, the most important are His humanlike activities — frolicking in Vrndavana, dancing with the gopis, playing with the Pandavas on the Battlefield of Kuruksetra and playing in Mathura and Dvaraka. And His most important pastimes in the human form are those in which He appears as a cowherd boy, a newly grown youth who plays a flute. Just a partial manifestation of His pastimes in Goloka — in Gokula, Mathura and Dvaravati, or Dvaraka — can overflood the whole universe with love of Godhead. Everyone can be attracted by the beautiful qualities of Krsna.
