sankirtana-yajne tanre bhaje, sei dhanya
sankirtana-pravartaka—the initiator of congregational chanting; sri-krsna-caitanya—Lord Caitanya Mahaprabhu; sankirtana—of congregational chanting; yajne—by the sacrifice; tanre—Him; bhaje—worships; sei—he; dhanya—fortunate.
Lord Sri Krsna Caitanya is the initiator of sankirtana [congregational chanting of the holy name of the Lord]. One who worships Him through sankirtana is fortunate indeed.
sei ta' sumedha, ara kubuddhi samsara
sarva-yajna haite krsna-nama-yajna sara
sei—he; ta'-certainly; su-medha—intelligent; ara—others; ku-buddhi—poor understanding; samsara—in the material world; sarva-yajna haite—than all other sacrifices; krsna-nama—of chanting the name of Lord Krsna; yajna—the sacrifice; sara—the best.
Such a person is truly intelligent, whereas others, who have but a poor fund of knowledge, must endure the cycle of repeated birth and death. Of all sacrificial performances, the chanting of the Lord's holy name is the most sublime.
Purport by Srila Prabhupada: Lord Sri Caitanya Mahaprabhu is the father and inaugurator of the sankirtana movement. One who worships Him by sacrificing his life, money, intelligence and words for the sankirtana movement is recognized by the Lord and endowed with His blessings. All others may be said to be foolish, for of all sacrifices in which a man may apply his energy, a sacrifice made for the sankirtana movement is the most glorious.
