Prabhupāda: So if this confidential knowledge, one who preaches without any compromise, he is the confidential servant of Kṛṣṇa. There is no compromise. This is real religion. The Kṛṣṇa says, na ca tasmān manuṣyeṣu kaścid me priya-kṛttamaḥ. So this is the person who has received the authority to draw mercy water from the ocean of mercy of Kṛṣṇa. Sākṣād-dharitvena samasta-śāstraiḥ. And what Kṛṣṇa said five thousand years ago, the same thing Caitanya Mahāprabhu said, same thing. There was no change, as there was no change between the statement of Viśvanātha Cakravartī Ṭhākura and Narottama dāsa Ṭhākura. Sādhu śāstra. As śāstra, there is no change. Not that "Modernize. The śāstra should be changed." No. That is nonsense. That is not śāstra. Śāstra cannot be changed. "Circumstantially, it will be changed, seasonal changes." No. That is not śāstra. Śāstra means it is perpetual. What Kṛṣṇa said five thousand years ago or Kṛṣṇa said some forty millions of years ago to the sun god... Imaṁ vivasvate yogaṁ proktavān aham avyayam (BG 4.1). He says, "I am talking to you that purātanaṁ yogam." Not that "Because it has passed millions of years and now it is a different time, so I will have to change." No. He said, "I am talking to you that very old system." Is it not? Just see. The śāstra cannot be changed. God's word cannot be changed. Then what will be the difference between God and ourself? He is always perfect. He is always perfect. What He said forty millions of years ago, what He said five thousand years ago, that is also correct up to date. That is śāstra. Not that "So many years have passed and it has become old. Now let us reform it and put it into new way." No. You can put the same thing in a new way, but you cannot change the principle. Sādhu śāstra guru-vākya, tinete kariyā aikya. Śāstra is never changed. And the sādhu... Sādhu means who follows the śāstras. He is sādhu. He also does not change. Sādhu, śāstra. And guru? Guru means who follows the śāstra and sādhu. So there are three, the same. A guru will not change, that "It was spoken five thousand years ago. That is not applicable now. Now I am giving you something new, jugglery." He is useless. Sādhu śāstra guru-vākya tinete kariyā aikya. Yaḥ śāstra-vidhim utsṛjya vartate kāma kārataḥ, na siddhim avāpnoti (BG 16.23). These things are there.
So the saṁsāra dāvānala-līḍha-loka **, these eight stanzas of Viśvanātha Cakravartī Ṭhākura is very important. We sing daily. That's very good. This world is dāvānala. Just like Ṛṣabhadeva, He wanted fire, He did not require any matches. No. Fire can be... By His will there will be fire. Formerly yajña fire was also ignited. What is that wood? Araṇi, yes. Not with matches. So it is ordinary thing, the friction of the bamboo, electricity. It creates electricity by friction. The electricity is also friction. Similarly, fire is created and the dry leaves of bamboo tree, they set in fire. Then, gradually, the whole forest is in blazing fire. And especially the snakes, they are the first sufferers. Because they remain on the ground and there are dry leaves and it takes fire very quickly, so they cannot fly away. Other animals, they can... Nobody can escape, but they can try because they can go fast. But the snake... Similarly, when there is catastrophe in the world, the persons like snakes, cruel, envious, they suffer first like a snake. Cāṇakya Paṇḍita has said, sarpaḥ krūraḥ khalaḥ krūraḥ. There are two envious living entities, very dangerous. What are they? One is snake. And another? The man whose habit is like snake. Without any fault he will bite. Without any fault.
So just like we are preaching Kṛṣṇa consciousness. So what is our fault? That we are trying to make men—no illicit sex, no gambling, no meat-eating, no intoxication, and they take it otherwise. They take: "It is very dangerous." Without any fault they are finding fault. This is snake. Sarpaḥ krūraḥ khalaḥ krūraḥ. No fault, but still fault-finding and giving us trouble. So you'll find so many persons, without any fault they'll bite. A snake, without any fault... You are passing, and you are taking some fruit from the tree. If there is snake, it will bite—the krūraḥ. So Cāṇakya Paṇḍita said, "There are two, two kinds of krūraḥ, envious living entities. One is the snake; another is the man-snake, or a man habituated to the snake quality." So sarpaḥ krūraḥ khalaḥ krūraḥ. But Cāṇakya Paṇḍita said, "This man snake is more dangerous than the animal snake." Sarpāt krūrataraḥ khalaḥ. Why? Now, mantrauśādhi-vaṣaḥ sarpaḥ khalaḥ kena nivāryate: "You can subdue the snake by chanting a snake mantra or some drug, jadi-bhuti(?), but this man-snake cannot be subdued." It is very, very dangerous.
