12 In this age, Krsna appears in his name in order to annihilate the demons and protect the devotees
Krsna has now appeared in His holy name through the Hare Krsna movement to annihilate the demons and protect the devotees:
[Vasudeva to Lord Krsna]: O my Lord, proprietor of all creation, You have now appeared in my house, desiring to protect this world. I am sure that You will kill all the armies that are moving all over the world under the leadership of politicians who are dressed as ksatriya rulers but who are factually demons. They must be killed by You for the protection of the innocent public.
Krsna appears in this world for two purposes, paritranaya sadhunam vinasaya ca duskrtam: [Bg. 4.8] to protect the innocent, religious devotees of the Lord and to annihilate all the uneducated, uncultured asuras, who unnecessarily bark like dogs and fight among themselves for political power. It is said, kali−kale nama−rupe krsna avatara. The Hare Krsna movement is also an incarnation of Krsna in the form of the holy name (nama−rupe). Every one of us who is actually afraid of the asuric rulers and politicians must welcome this incarnation of Krsna:
Hare Krsna Hare Krsna Krsna Krsna Hare Hare
Hare Rama Hare Rama Rama Rama Hare Hare
Then we will surely be protected from the harassment of asuric rulers. At the present moment these rulers are so powerful that by hook or by crook they capture the highest posts in government and harass countless numbers of people on the plea of national security or some emergency. Then again, one asura defeats another asura, but the public continues to suffer. Therefore the entire world is in a precarious condition, and the only hope is this Hare Krsna movement. Lord Nrsimhadeva appeared when Prahlada was excessively harassed by his asuric father. Because of such asuric fathers that is, the ruling politicians it is very difficult to press forward the Hare Krsna movement, but because Krsna has now appeared in His holy name through this movement, we can hope that these asuric fathers will be annihilated and the kingdom of God established all over the world. The entire world is now full of many asuras in the guise of politicians, gurus, sadhus, yogis and incarnations, and they are misleading the general public away from Krsna consciousness, which can offer true benefit to human society.
– Srimad Bhagavatam 10.3.21
Just as formerly Krsna appeared personally to decrease the military burden on the earth, He has now appeared by His name in the Hare Krsna movement for the same purpose:
In this verse from Srimad Bhagavatam we find the words puraiva pumsavadhrto dhara jvarah. The word pumsa refers to Krsna, who was already aware of how the whole world was suffering because of the increase of demons. Without reference to the supreme power of the Personality of Godhead, the demons assert themselves to be independent kings and presidents, and thus they create a disturbance by increasing their military power. When such disturbances are very prominent, Krsna appears. At present also, various demoniac states all over the world are increasing their military power in many ways, and the whole situation has become distressful. Therefore Krsna has appeared by His name, in the Hare Krsna movement, which will certainly diminish the burden of the world. Philosophers, religionists, and people in general must take to this movement very seriously, for man made plans and devices will not help bring peace on earth.
