Harinama in Moscow (Album with photos)
Srila Prabhupada: For those who are interested in Krishna consciousness, it is clearly stated that they should chant sixteen rounds every day. You are not Haridasa Thakura, you are not able to chant all day and all night; although it is a lofty ideal, it is something which at present you cannot do. Sixteen rounds of japa is the minimum requirement and that takes no more than two hours. That leaves twenty-two hours to spend in Krishna’s service. That is required for progress in Krishna Consciousness. (Bhagavad-gita, 9.14 Lecture)
