Nama Sankirtana and Karma Yogam Part2

Is Nama Sankirtana is by itself sufficient to remove all our sins?
Nama sankirtanam removes the indifference we have towards bhagavan, his devotees and the spiritual concept of Life, it provides us with the mental strength, power of endurance and a clear frame of mind to make us qualified to begin  Varnasrama Dharma(Karma Yoga)-->by which Bhagavan becomes pleased--> hence he removes all our papa,punya and takes us back to his spiritual abode(Vaikuntha).
Say for a Kshatriya, Nama sankirtanam gives us all basic qualifications a kshatriya needs to defeat the allies of Adharma and establish Dharma. Endowed with all basic qualities unless a kshatriya fights the war(which is his Karma Yogam), his enemies cannot be defeated, similarly endowed with all auspicious qualities, unless one executes his Karma Yogam-->Bhagavan will not remove his eternal enemy which is nothing but his papa and his punya.
Unless one is purified of these misgivings(papa,punya) one will not be able to go back home back to Godhead(Vaikuntha).

How to become Immune from Infection of the Material World?

There is no doubt that this Material world is infected with the disease of Greed, Pride, envy,ego, ignorance which is nothing but the Product of the Mode of Passion(Rajo Gunam) and the Mode of Ignorance(Tamo Gunam).
For an aspiring transcendentalist, becoming free from their influence is a must to rise to the spiritual platform of Pure Love of God situated above the Mode of Goodness.
Out of his causeless mercy, Sriman Narayana(The Supreme Personality of Godhead) mercifully incarnates as the Archa Vigraha in Temples, as spiritual Masters(Vaishnavas), spiritual books, his Holy Names, offering and partaking of Vishnu Prasadam which are of the form of Pure Goodness(without contamination of Mode of Passion and Ignorance) which aspiring transcendentalists could constantly meditate and become immune from he Infections of the material world.
