We have established the International Society for Krishna Consciousness, in which the methods of attaining divine consciousness are taught. In this society we invite everyone to come and chant Hare Krsna. This process is not difficult, and even children can participate. No previous qualifications are necessary; one doesn’t need a master’s degree or doctorate. Our invitation to everyone is to join this association and become Krsna conscious.
