The process for Krishna consciousness is that we control the mind through hearing and chanting. We hear the maha mantra, Hare Krishna Hare Krishna Krishna Krishna Hare Hare Hare Rama Hare Rama Rama Rama Hare Hare and we hear the lectures from the spiritual master and read his books. Also we speak by preaching and by chanting. This is the easy method for controlling the mind, by hearing and chanting.
