If we observe strictly the rules and regulation of kula-dharma . . . kula-dharma means if you are a brāhmaṇa, you must observe the regulative principles, the qualitative principles of a brāhmaṇa. If you are in . . . a kṣatriya, then you must also observe the kṣatriya principles. All these are described in the Bhagavad-gītā, who is brāhmaṇa, who is kṣatriya, by symptoms. By symptoms we have to accept whether one is brāhmaṇa or kṣatriya or vaiśya, not by birth. That is the injunction of the śāstra.
So this has to be observed. If we want actually deliverance from this material entanglement, so these rules and regulations of kula-dharma we must observe. If we do not observe, then immediately we become irreligious. Dharme naṣṭe kṛtaṁ kṛtsnam adharmam abhibhavati iti uta. Uta, Arjuna said: "It is said." He has learned from higher authorities. Uta. "It is said" means "Said by authorities." So "If adharma, irreligious life, is propagated on account of loss of kula-dharma, then everything is lost, my dear Kṛṣṇa. So why shall I kill?" Other things also will be described later on, that the . . . when the male members are killed, the female members become widow, and they, their character becomes polluted. So many things Kṛṣṇa will speak about this family life.
So at the present moment, there is no such family life, no consideration of religion, no consideration of irreligious life. Everything just like animals. Kalau śūdra-sambhavaḥ. If not animals, they are all śūdras; nobody brāhmaṇa, nobody kṣatriya, nobody vaiśya. So it is a chaotic condition of the human society. Therefore it cannot be revived to the original position of systematic institutional position. It is not possible. Everything is lost. Therefore by the Caitanya Mahāprabhu's grace, one thing:
- harer nāma harer nāma harer nāmaiva kevalam
- kalau nāsty eva nāsty eva . . . gatir anyatha.
- (CC Adi 17.21)
Everything is lost. Now, simply by chanting harer nāma, the holy name of Lord Kṛṣṇa, you become again situated in the original position. Everything is adjusted, because it is transcendental. So there is no other way.
Caitanya Mahāprabhu is so merciful that from the śāstras he has selected this process of saṅkīrtana movement: ceto-darpaṇa-mārjanam bhava-mahā-dāvāgni-nirvāpanam (CC Antya 20.12). The human life is meant for extinguishing the blazing fire of material existence. But we are not in regulative principles. We have lost everything—our sanātana-kula-dharma, everything. Under the circumstances, Caitanya Mahāprabhu gives us the greatest facility according to śāstra. That is the boon of this age: kīrtanād eva kṛṣṇasya mukta-saṅgaḥ paraṁ vrajet (SB 12.3.51). Simply by chanting the holy name of Kṛṣṇa, everyone becomes free from all contamination of this age, mukta-saṅgaḥ paraṁ vrajet. And he becomes so purified that he becomes fit to go back to home, back to Godhead.
So this opportunity, chanting of Hare Kṛṣṇa mantra, we should not miss. We should . . . we must. Where is the difficulty, Hare Kṛṣṇa chanting? Kīrtanīyaḥ sadā hariḥ. Tṛṇād api sunīcena taror api sahiṣṇunā (CC Adi 17.31). This is the only savior for the human society of this age.
