The simple method is this chanting, Hare Kṛṣṇa. You keep yourself chanting as many hours, twenty-four hours. Why as many hours? Twenty-four. Kīrtanīyaḥ sadā hariḥ (CC Adi 17.31). Lord Caitanya says: "This is to be practiced twenty-four hours." And that you can do. It requires simply practice. Even in sleeping you can chant Hare Kṛṣṇa. Even in sleeping. And there is no bar. In sleeping, in eating, in going to the toilet room, there is no restriction. You can go on chanting, "Hare Kṛṣṇa." You see? So that will keep you in your svarūpa, in your real identification, and you'll never be attacked by māyā.
Just like if you keep yourself vaccinated, and if the period . . . what is called? Active. Then there is no fear of being infected. That is practical. If you get yourself vaccinated of certain type of infection and you keep yourself active . . . just like doctors, they go, treat patients suffering from infectious disease, but they keep themselves always unaffected. They know the remedial measures, antiseptic, prophylactic processes.
So this prophylactic antiseptic process is kṛṣṇa-kīrtanam. Paraṁ vijayate śrī-kṛṣṇa-kīrtanam. That is Lord Caitanya's blessings. Paraṁ vijayate. All glories to the saṅkīrtana, śrī-kṛṣṇa-saṅkīrtana. Kīrtana means kṛṣṇa-kīrtana. Not any other kīrtana. The Māyāvādī philosopher, they introduce so many other kīrtanas. No.
Kīrtana means kṛṣṇa-kīrtana: Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma . . . or any name glorifying the name of the Lord. That is kīrtana. But this Hare Kṛṣṇa mantra is especially recommended in this age, and Lord Caitanya personally chanted, so we should follow.
