Your sign reads "The Perfection of Yoga," actually that is a fact. Bhakti-yoga is the best. Yoginam api sarvesam, madgatenantaratmana . . . [Bg. 6.47]. This Hari-kirtana is the best yoga, bhakti-yoga. You just follow our regulative principles and teach others and you will be successful, without any doubt.

From Srila Prabhupada's letter to: Caitya-guru — New York 11 July, 1976
