In this age it is very difficult, but if one chants Hare Kṛṣṇa mahā-mantra without any offense, being trained up by the spiritual master, all the saṁskāras automatically become done, and he comes to his original spiritual position, ahaṁ brahmāsmi, "I am spirit soul. The Kṛṣṇa is Param Brahman, and I am Brahman." As Arjuna said, paraṁ brahma paraṁ dhāma pavitraṁ paramaṁ bhavān (BG 10.12). Kṛṣṇa is also Brahman, I am also Brahman. But He's Supreme Brahman, I am minute Brahman. So my business is to serve Kṛṣṇa." That is teachings of Lord Caitanya, jīvera 'svarūpa' haya nitya kṛṣṇa-dāsa (CC Madhya 20.108). So if he engages himself in his original spiritual business, to act as the servant of Kṛṣṇa, then all reformation is done.
So that advantage is given in this age: kīrtanād eva kṛṣṇasya mukta-saṅgaḥ param . . . (SB 12.3.51). Reformatory process is meant for purifying him so he becomes mukta-saṅgaḥ. Mukta-saṅgaḥ means liberated from all this bad association of material existence. And he becomes eligible to go back to home, back to Godhead. So this is the special advantage. The question is, "Whether they should be revived?" They should be revived to the lowest necessity, but all of them cannot be revived in this age. But people should be induced to take to chanting Hare Kṛṣṇa maha-mantra. Then all reformation will automatically become manifest, and he will come to spiritual platform, brahma-bhūtaḥ, the realization of Brahman. Then prasannātmā, he'll be happy. There is no lamentation, there is no undesirable hankering. Na śocati na kāṅkṣati. He sees everyone on the spiritual platform. Samaḥ sarveṣu bhūteṣu. In this way he comes to the platform of devotional service, and then his life becomes successful.
