He wanted it. Because this is the only message to bring the human society into oneness. There is no other alternative. That is confirmed in the Srimad-Bhagavatam:

So this Kali-yuga, as described by our Gaura-Govinda Maharaja, a bhankara (?) yuga. But there is one opportunity, kirtanad eva krsnasya mukta-sangah param vrajet. This is the message of Sri Caitanya Mahaprabhu, and a little attempt was made at the age of seventy years. Of course, my Guru Maharaja asked me... When I was twenty-five years old, I first met him. He asked me to do this task. But I thought that "Let me adjust my family life, and then I shall do this." But I took it very seriously. But family life, never it was adjusted, so he forced me at the ripe old age to take up this work. So I tried to make an experiment that nobody had done: "Let me try." But I tried sincerely, so by the grace of my Guru... Guru-Krsna, they favored me. When I was on the Commonwealth Jetty, Pier, yes, I was thinking that "Who will hear me? As soon as I shall say to these people that 'No illicit sex, no meat-eating, no intoxication and no gambling,' immediately they will say, 'Please go home. Don't talk here.' " Because I know that. This is their daily life. But by the grace of Krsna they agreed. All these students, all these disciples... I do not accept anyone as my disciple that "You can do whatever you like." No. My first condition is that "You must be sinless." At least you must try to become sinless, because in the Bhagavad-gita we understand,

Without being sinless, one cannot make any advance.

So in this age practically there is nil who is a dhira. Everyone is adhira. But the sankirtana movement is so nice, as it is spoken by Srinivasa Acarya on behalf of Narottama dasa Thakura, krsnot-kirtana-gana-nartana parau premamrtambho-nidhi dhiradhira-jana-priyau. This movement is so nice that it will be pleasing to the dhiras and the adhiras.

So the disease is there, but the remedy is also there. Ceto-darpana-marjanam [Cc. Antya 20.12]. We are misunderstanding. The human society, they are trying to adjust things by the United Nations, but it is not possible. United Nations cannot do. In Melbourne I was speaking, so I accused the United Nations, "They're assembly of barking dogs." Because you cannot be united on this material platform. If you keep yourself that "I am dog," "I am tiger," "I am American," "I am Indian," "I am brahmana," "I am sudra," then there is no question of United Nations. United Nations is possible when sarvopadhi-vinirmuktam tat-paratvena nirmalam [Cc. Madhya 19.170]. You have to become purified on Krsna consciousness, not "I am American," not "I am Indian." No. This will not help.

So factually we see that these Americans, Europeans, they are Christian, Jews, or there are Muhammadans also in our movement, Africans, all over the world, but they no more think that he is African or Indian or American. They think Krsna dasa. As Caitanya Mahaprabhu taught us, jivera svarupa haya nitya krsna dasa [Cc. Madhya 20.108-109]. Unless we come to that platform, that we are servants of Krsna, there is no question of unity. That is brahma-bhutah stage.

Unless you come to that brahma-bhutah stage, that "I am not this body. I am soul, aham brahmasmi. I am part and parcel of the Supreme Brahman"param brahma param dhama pavitram paramam bhavan [Bg. 10.12]there is no question of unity. So Caitanya Mahaprabhu wanted to introduce this movement how actually there can be possibility of being united. That is possible. That is not difficult because they are all sons of Krsna. Sarva-yonisu kaunteya sambhevanti..., aham bija-pradah pita [Bg. 14.4]. He's the original father. So this Krsna consciousness movement is trying to introduce in the human society, and not on my conviction, on the assurance of the sastras, that if you want to be united, you'll have to come to this platform of Krsna consciousness; otherwise it is not possible.
