Srila Rupa Gosvami has described Sri Caitanya Mahaprabhu as maha-vadanya-avatara, the most munificent incarnation. Although Sri Caitanya Mahaprabhu is not physically present now, simply by chanting His holy name (sri-krsna-caitanya prabhu nityananda sri-advaita gadadhara srivasadi-gaura-bhakta-vrnda) people throughout the world are becoming devotees. This is due to the ecstatic chanting of the holy name of the Lord. It is said that a pure devotee can see the Lord every moment, and because of this he is empowered by the Lord. This is confirmed in the Brahma-samhita: premanjana-cchurita-bhakti-vilocanena santah sadaiva hrdayesu vilokayanti. Sri Caitanya Mahaprabhu appeared five hundred years ago, but it cannot be said that now the potency of the Hare Krsna maha-mantra is less powerful than it was in His presence. By hearing Sri Caitanya Mahaprabhu through the parampara system, one can be purified. Therefore in this verse it is said: tathapi tanra darsana-sravana-prabhave. It is not that everyone is able to see Krsna or Sri Krsna Caitanya Mahaprabhu physically, but if one hears about Him through books like Sri Caitanya-caritamrta and through the parampara system of pure Vaisnavas, there is no difficulty in becoming a pure Vaisnava, free from mundane desires and personal motivations.
