The Kṛṣṇa says, na ca tasmān manuṣyeṣu kaścid me priya-kṛttamaḥ (BG 18.69). 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 is 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. So this is . . . 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.
