The descent of Sri Krsna, the Absolute Personality of Godhead, is very purposeful. In the Bhagavad-gita it is said that one who knows the truth about Sri Krsna's descent and His various activities is at once liberated and does not have to fall again to this existence of birth and death after he leaves his present material body. In other words, one who factually understands Krsna makes his life perfect. Imperfect life is realized in material existence, in five different relationships we share with everyone within the material world: neutrality, servitorship, friendship, filial love, and amorous love between husband and wife or lover and beloved. These five enjoyable relationships within the material world are perverted reflections of relationships with the Absolute Personality of Godhead in the transcendental nature. That Absolute Personality, Sri Krsna, descends to revive the five eternally existing relationships. Thus He manifests His transcendental pastimes in Vraja so that people may be attracted into that sphere of activities and leave aside their imitation relationships with the mundane. Then, after fully exhibiting all such activities, the Lord disappears.
