We don’t discourage you to construct big, big cars, but it should be used for the kirtana party to go to village to village, not to go to the brothels and liquor shop. Then you are ruined. You can use it, all the facilities. The microphone should be used for spreading Krsna consciousness, not talking nonsense. This should be this… Everything is good, provided it is used for good purpose. Nirbandhe krsna sambandhe yukta vairagyam ucyate. We are not such foolish person that “This is material, this microphone. We shall not touch it.” No, we are not so fool. We are intelligent enough how to use it.
