It is simultaneously one and different. Hearing the tape certainly the sound vibration is same as what is in class. So, it is very, very purifying and very important but when the opportunity is there. However, when you are in a class and there is a satsang of so many devotees, all offering their combined devotional attention to the speaker, that atmosphere is very, very important. It is very special and very purifying to our heart. Hearing tapes is very important but it cannot substitute for going to the classes. It should be there whenever the opportunity, wherever we are we listen to tapes, it would be very, very wonderful. But still coming to the class and being in the association of many devotees all utilizing their combined devotional efforts to reciprocate with the Srimad Bhagavatam it is very purifying environment, we should be eager to participate in whenever possible. Is that answer your question?
