Lord Caitanya declares a war against Kali Yuga with "the bow" "the six Goswamis", by pulling back "the string" "Bhakti Vinod Thakur" making a thunderous sound, puts "the long strong arrow" "Bhakti Siddhanta Saraswati Thakur", having "the direction giving feather back of the arrow" "Sri Gaur Kishore Das Babaji Maharaj" and "the sharp penetrating arrow front" "Srila A.C.Bhakti Vedanta Swami Prabhupada".
To manage a sankirtana party nicely is more precious than all other activities. That is the verdict of Bhagavad-gita and the mission of Lord Sri Chaitanya Mahaprabhu.
Letter to Tamala Krsna – Bombay 13 November, 1975.
Chaitanya Mahaprabhu is the incarnation of the Supreme Personality of Godhead in this age of Kali, and He will be easily satisfied if the sankirtana movement is spread vigorously all over the world.
Purport Srimad Bhagavatam on 8.14.6
Lord Chaitanya has given special stress to chanting of these holy names of the Lord as the basic principle of spiritual advancement.
Purport on Srimad Bhagavatam 3.29.18
The entire Krishna consciousness movement is based on the principles of the sankirtana movement inaugurated by Sri Chaitanya Mahaprabhu. Therefore one who tries to understand the Supreme Personality of Godhead through the medium of the sankirtana movement knows everything perfectly.
Purport on Srimad bhagavatam 7.9.38
Sri Chaitanya Mahaprabhu is the inaugurator of the sankirtana movement, anyone who performs sankirtana to please the Lord is very, very glorious. Such a person has perfect intelligence, whereas others are in the ignorance of material existence.
Purport on Srimad Bhagavatam 5.19.24
