Because He knew, in this age, Kali Yuga, who is going to observe this varnasrama-dharma? Everyone is sudra. A sudra cannot understand this, neither it is possible to bring them back again. Although we are trying, but it is very difficult. Once one has become debauch, to reform him is very difficult. But still there is way. And that way is suggested when... Ramananda Raya suggested that... It is the words of Lord Brahma that jnane prayasam udapasya: "One should not very much endeavor to speculate, speculating process." Just like these theosophists, the philosophers, the scientists. They, instead of having direct knowledge from the superior, they, more or less, speculate. So one has to give up this speculating habit. If one thinks that "I know. I am very educated. I am very advanced. I can discover what is God," that is not possible. That is not possible. Athapi te deva-padambuja-dvaya-prasada-lesanugrhita eva hi janati tattvam [SB 10.14.29]. You cannot understand God by your speculative method. Big, big scholars, they have speculated about Krsna in the Bhagavad-gita. Misled, they could not understand.   (More...)

So in order to get the mercy of guru, so yasya prasadad bhagavat-prasadah **, we must search out a bona fide spiritual master, representative of Krsna or Kapiladeva, and then we shall submit and offer service. In this way we shall please the guru, and if he is satisfied, then our business is complete. Yasya prasadad bhagavat-prasado yasyaprasadan na gatih kuto 'pi **. Therefore Caitanya Mahaprabhu recommended this process, this process, jnane prayasam udapasya namanta eva. The process of understanding or approaching the Supreme Personality of Godhead is this. Caitanya Mahaprabhu approved this when He was discussing with Ramananda Raya. So the process of approaching the Supreme Lord... So he first of all explained the varnasrama-dharma. Varnasramacaravata purusena parah puman, visnur aradhyate [Cc. Madhya 8.58]. The human life is for visnur aradhanam. That is the human life, Visnur aradhanam. In varnasrama, the system... Catur-varnyam maya srstam [Bg. 4.13], Krsna says. Why establish this catur-varnyam maya srstam? Because through the catur-varnya, systematic institution, following the rules and regulations of brahmana, ksatriya, vaisya, sudra, one can approach Lord Visnu. Visnur aradhyate. This varnasrama-dharma is very important. But Caitanya Mahaprabhu said that it is very difficult even to execute the rules and regulation of varnasrama-dharma in this age. Actually that is a fact. Therefore, after explaining varnasrama-dharma before Caitanya Mahaprabhu, He said, Caitanya Mahaprabhu said, eho bahya: "Yes, it is one of the processes, but in this age it is very difficult." Who is going to be brahmana? It is very difficult. Especially it has become very difficult in India. We are advertising, we are soliciting, "Please come here in this Hare Krsna Land and just become a brahmana-vaisnava, and we shall try to serve you by giving you good place," but nobody is coming. Therefore it is very difficult to revive the old varnasrama-dharma culture.   (More...)
