How we utilize our time is what qualitatively makes human life great.
One who is sufficiently intelligent should use the human form of body from the very beginning of life, in other words, from the tender age of childhood, to practice the activities of devotional service, giving up all other engagements. The human body is most rarely achieved and although temporary like other bodies, it is meaningful because in human life one can perform devotional service. Even a slight amount of sincere devotional service can give one complete perfection.
We should know in perfect consciousness that human life is bestowed upon the conditioned soul to achieve spiritual success and the easiest possible procedure to attain this end is to chant the holy name of the Lord.
The bestial civilization of eating, sleeping, fearing and sense-gratifying has misled modern man into forgetting how powerful a soul he is. The soul is a spiritual spark many, many times more illuminating, dazzling and powerful than the sun, moon, or electricity. Human life is spoiled when man does not realize his real identity with his soul.
Human species are most rare species because this offers us the most rare opportunity of coming to temple or coming to god or thinking of god, hearing about god or this dharma business, this religion business is only for human beings.
Without becoming a devotee of the Lord, one cannot perfect one's human life. The perfection of human life is to be elevated to the spiritual world, where there is no birth, no death, no disease and no old age. Without this aim, any amount of material advancement in so-called comforts can only bring the defeat of the human form of life.
