So this mantra is required, the Vedic mantra, to hear mantra. This chanting of these verses is also hearing the Vedic mantra. So we should take chance, and the most important mantra is maha-mantra. Maha-mantra. We are sleeping, but this maha-mantra, Hare Krsna, if we hear somehow or other... Therefore the greatest beneficial activity or welfare activity is to chant this Hare Krsna maha-mantra so that others can hear. But unfortunately, when we chant loudly, others they think, "It is nuisance." That is the difficulty. But actually it is the process of awakening: "Get up, get up, get up, get up." Ceto-darpana-marjanam. If we hear this mantra, Hare Krsna maha-mantra, then the mistaken ideas... Ceto-darpana-marjanam: [Cc. Antya 20.12] cleansing the mirror of the heart.
