The whole process is, of this Krishna Consciousness movement, to meet the waves of material nature. The waves are called agitation by hunger and thirst, lamentation, confusion, illusion in so called love and affection, pangs of old age and disease and at last meeting with death. All these things can be changed simply by engaging ourselves in the service of the Lord which keeps us always in the transcendental position. Some way or other if we are able to keep in the transcendental position by devotional service we remain completely untouched by the contamination of matter. By the grace of Lord Caitanya things have been reduced to a very easy operation: by chanting Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare, Hare Rama, Hare Rama, Rama Rama, Hare Hare.
