Caitanya Mahaprabhu's Siksastakam, Mahamantra Potency

July 16: Mahaprabhu's Siksastakam

Caitanya Mahaprabhu is one of the strong advocates of SB, because the nature of living entity is to serve Krishna.
We have same quality as Krishna, but we are very very small in quantity. To this Supreme soul, we should serve with everything.

Caitanya Mahaprabhu's 8 verses:
First: How do we attain that self-realization, that we are not the body and are spirit souls. Caitanya Mahaprabhu did not start the sankirtan movement whimsically...
Going back to Godhead after attaining self-realization is possible, by chanting the Hare Krishna Mahamantra.

Kaliyuga process: Sankirtan
Sages gave up fire sacrifices, started chanting the Holy Name. And what is the mantra of the Kaliyuga:
Hare Krishna Hare Krishna Krishna Krishna Hare Hare
Hare Rama Hare Rama Rama Rama Hare Hare

In Kalisantarana Upanishad: This mantra is given as
Hare Rama Hare Rama Rama Rama Hare Hare
Hare Krishna Hare Krishna Krishna Krishna Hare Hare

So why do we chant the other way: This is so because:
As it is given in the Kalisantaran Upanishad, it will remove only the impurities of Kaliyuga of quarrel and hypocrisy. But Caitanya Mahaprabhu since he Krishna in his most munificent form and is Radharani also, he added Krishna prema into this mantra. He accepted it and added the Krishna prema potency... and gave us
Hare Krishna Hare Krishna Krishna Krishna Hare Hare
Hare Rama Hare Rama Rama Rama Hare Hare

Now, it not only removes the influence of Kaliyuga, but also gives Love of Godhead.
