Chanting the holy name is the Yuga-dharma. Supreme Lord Sri Krishna descended as Sri Chaitanya Mahaprabhu to inaugurate this dharma and propagate the Sankirtana Movement. He desired that the entire world be inundated with the chanting of the holy name.
Sri Chaitanya Mahaprabhu said: ceto-darpaṇa-mārjanam bhava-mahā-dāvāgni-nirvāpaṇam — chanting cleanses the mirror of the heart and extinguishes the blazing fire of material existence.
Following Srila Prabhupada, Hare Krishna Movement Tirupati conducts FOLK, Harinam festivals, Hare Krishna flash mobs and public kirtan so as many people as possible take up the maha-mantra.
