Harinam Sankirtan: The greatest gift to this world
Harinam Sankirtan is Lord Caitanya Mahaprabhu’s gift to this world in this particular Kali-yuga and it’s very rare.
There are 1000 Kali-yuga’s in one-half day (day-time only) of Lord Brahmas time.
It takes 4 billion 320 million human years to travel through 1000 Maha-yugas (A cycle of Satya, Treta, Dvāpara and Kali-yuga’s) which happens in 12 hours of Lord Brahma’s day-time period from sunrise to sunset.
Then add the same duration of time (4 billion 320 million earth or human years) for Brahma’s inactive 12 hour night from sunset to sunrise to eventually see that Lord Caitanya appearance in just one Kali-yuga, the same Kali-yuga we are in now, is very, very rare.
Lord Caitanya does not appear in the other 999 Kali-yugas that all occurs during Brahma’s day from sunrise to sunset.
A 24 hour day-night period of Brahma happens over a period of 8 billion 640 million human years
There are no yugas during Brahma’s 12 hour night time period while he sleeps. Also the time between Brahma’s sunset and sunrise is when this material universe experiences a partial annihilation which happens over a period of 4 billion 320 million human years.
So one day-night 24 hour period of Brahma equals 8 billion 640 million human years as already explained.
Lord Caitanya therefore comes “once” in a day-night time of Lord Brahma and so does Krishna in His original Form at the end of a Dvāpara-yuga.
