One mahamantra contains 16 names of Krishna: Hare Krsna Hare Krsna, Krsna Krsna Hare Hare, Hare Rama Hare Rama, Rama Rama Hare Hare!
If you chant this mantra 108 times on beads, it is called one round. That equals 1728 names of Krishna.
If you chant one round daily in Kartik (Oct 5 through Nov3=30 days), you would have called out to Krishna over 51,000 times in Kartik.
If you chant 10 rounds daily in Kartik, you would have chanted over half a million names of Krishna in Kartik.
If you chant 20 rounds daily in Kartik, you would have chanted over a million names of Krishna in Kartik.
