The man does not know God as he really is, and ignores the nature of its universality.
The man ignores any data on the absolute truth, the pure spiritual science that God has revealed, and has only a vague idea of his divine teaching, for it to undergo multiple changes, and passages deleted.
The man still does not know that it is, indeed, a spiritual entity or spirit soul, hence its propensity to cling to the material world, to remain there, and to suffer continuously.
We can become the greatest spiritualist, the greatest sages, while remaining a fighter. How is this possible ?
By Krishna consciousness. Just fight for Krishna, work for Krishna, Krishna to eat, sleep Krishna and dedicate all activities to Krishna. Here's how one becomes the greatest of spiritualists and the greatest sages. This is the secret.
The thought to Krishna is the essence of all yogas (spiritual actions) whether sacrifice or charity.

When progressing tangible through such a mode of action, it reached a level where even when it is not physically, it remains active internally by constantly thinking of Krishna. As long as one has not reached this level, however, it is highly recommended to always engage the senses in Krishna's service. There are actually a variety of activities can be accomplished by serving Krishna. For those who act in Krishna consciousness, there is simply not enough hours in a day to serve Krishna. Day and night, Krishna consciousness of students complete a thousand activities, and in the greatest joy. This is also the true happiness always work for Krishna and strive to spread Krishna consciousness throughout the world. In the material world, one can run out to work hard, but when we act in the consciousness of Krishna, Hare Krishna can sing and devotional service twenty-four hours twenty-four without getting tired . In contrast, when it is vibrated as a purely hardware-inspired sounds, we soon run out. Spiritually, by cons, there is no question of fatigue; spiritually is absolute. In the material world, everyone is in order to satisfy his senses; all the fruits of our labor are used for sensory gratification. But the real devotee does not wish to reap such fruit; it nurtures no desire outside of Krishna, and Krishna is always there.
