One may argue that, "Where is Caitanya Mahāprabhu now? Where is Kṛṣṇa now?" It doesn't matter. Kṛṣṇa's words are there. Caitanya Mahāprabhu's words are there. Instructions are there. So if we follow the direction and instruction of Caitanya Mahāprabhu or Kṛṣṇa under the guidance of a superior, bona fide spiritual master, then we associate with Kṛṣṇa or Caitanya Mahāprabhu without any deviation.
So "lowest of the mankind . . ." Now if somebody is not Kṛṣṇa conscious, and if we say that, "You are lowest of the mankind," a very, very strong word used . . . A gentleman, suppose he's not a devotee of Kṛṣṇa, but if we say that "You are the lowest of the mankind," he'll be certainly very angry that, "I am such a nice gentleman, and you are talking of me as the lowest of the mankind." But actually the fact is this.
Tāvac ca śobhate mūrkho yāvat kiñcin na bhāsate, sabhāyaṁ vastra-veṣṭhitaḥ. There is a moral instruction that a so-called gentleman, nicely dressed in the assembly of human society, may appear to be very nice so long he does not speak. But he's . . . if he speaks nonsense, without Kṛṣṇa consciousness, immediately he becomes the lowest of the mankind.
