The present age is called Kali-yuga. Kali-yuga means the age of quarrel and disagreement. Nobody agrees with any other man. Everyone has got his own theory; everyone has got his own philosophy. So therefore it is called Kali-yuga. And if I don't agree with you, you fight with me. Therefore it is called Kali-yuga. So this is the only method recommended in this age: kalau tad dhari-kīrtanāt. Simply by chanting the holy name of God, one can attain perfect self-realization, which was attained by the yoga system in the Satya-yuga, which was attained in the Tretā-yuga by performing great sacrifices, and which was performed in the Dvāpara-yuga by large-scale temple worship. That thing can be attained by the simple method hari-kīrtanāt. Hari means the Supreme Personality of Godhead; kīrtanāt—by glorifying Him. This is the method recommended in the śāstras. And Lord Caitanya Mahāprabhu, five hundred years ago, He appeared in a town which is known as Navadvīpa. It is about sixty miles northern side of Calcutta. People still go there. We have got our temple, center there. It is also a sacred pilgrimage. So Caitanya Mahāprabhu appeared there, and He started this saṅkīrtana movement, mass saṅkīrtana movement, without any discrimination. And He predicted that this saṅkīrtana movement would be spread all over the world and the Hare Kṛṣṇa mantra would be chanted in every village, town on the surface of the globe.
So in pursuance of the order of Lord Caitanya Mahāprabhu, following His footsteps, we are trying to introduce this saṅkīrtana movement, Hare Kṛṣṇa, and it is coming out very successful. Everywhere. I am especially preaching in the foreign countries. All over Europe, America, Japan, Canada, Australia, I am traveling. Malaysia. And anywhere I have introduced this saṅkīrtana movement—we have got different centers, about sixty centers—they have been received with great pleasure. Just like you saw these boys and girls. I have not imported them from India, but they have taken this movement very seriously, and they will take it, because it appeals to the soul directly. We have got different status of our life. Bodily concept of life, mental concept of life, intellectual concept of life and spiritual concept of life. So actually we are concerned with the spiritual concept of life, athāto brahma jijñāsā. If you are allured by the bodily concept of life, then we are no better than these dogs and..., cats and dogs. Yasyātma-buddhiḥ kuṇape tri-dhātuke (SB 10.84.13). If we accept that "I am this body," then we are no better than the cats and dogs, because their concept of life is like that.
When we understand that "I am not this body...," As Kṛṣṇa wanted to impress upon Arjuna in the beginning of His teaching of Bhagavad-gītā: "First of all try to understand what you are. Why you are lamenting in the bodily concept of life? You have to fight. Certainly you have to fight with your brothers and brother-in-laws and nephews, other side. And you are lamenting. But first of all understand whether you are body or not." That is the beginning of Bhagavad-gītā. He tried to make him understood that you are not body. So these instructions were not for Arjuna. For everyone. We have to first of all learn that "I am not this body. I am spirit soul."
