Glories of sankirtan movement

kali-kalera dharma—Krishna-nama-sankirtana
krishna-shakti vina nahe taara pravartana
TRANSLATION
“The fundamental religious system in the Age of Kali is the chanting of the holy name of Krishna. Unless empowered by Krishna, one cannot propagate the sankirtana movement.
Antya Lila 7.11

Sri Caitanya Mahaprabhu set a practical example in that He did not establish any temples or Deities, but He profusely introduced the sankirtana movement. Therefore Krishna consciousness preachers should give more stress to the sankirtana movement, especially by distributing transcendental literature more and more. This helps the sankirtana movement.
