Hare Krsna Hanumatpresaka Maharaja,
please accept my respectful obeisances,
all glories to Srila Prabhupada!

At first i'd like to thank you for your very useful answers, help and example.

and here is a new question about japa:
We know that Srila Prabhupada gave us the (@least) 16 rounds, and Srila Bhaktisiddhanta Sarasvati Thakura gave 64, and Sri Caitanya Mahaprabhu also chanted His rounds.
My question is that where this chanting process comes from?
Who introduced it to the human society? Is there any information about the origin of chanting Hare Krsna?

Thank you very much,
your servant: Kadamba Kanana dasa

      HpS - AGTSP   paoho.   Well the verses like "harer nama, harer nama...", in Caitanya caritamrta Adi Seven the mention by Lord Caitanya to Prabodhananda Sarasvati how his guru gave him Japa.  In BG chapter 10 mentions japa, no?

In so many Puranas, Tantras etc. well find it.  Narada's instructions to Dhruva in the 4th Canto.  The sources for the specific Maha mantra is also in purports in ADI seven also I think.  Read that Chapter. I think you'll find it SUPER!
