The human being must understand that it is imperative that he establishes himself on the spiritual and absolute level, where neither time nor material energy exert their influence. He must re-establish his bond with the Lord and re-establish his relationship with God. He is meant to achieve spiritual realisation and to re-establish his forgotten relationship with God. Human life offers the opportunity for all of us, as embodied and conditioned souls, to regain our eternal spiritual consciousness and thus complete the mission of existence.
The human form is especially meant for the unfoldment of the consciousness of Krishna, God, the Supreme Person, because this divine consciousness will enable us to regain our spiritual body, all bliss, knowledge and eternity. The purpose of Krishna consciousness or God consciousness is to give us a body of the same nature as that of Krishna Himself.
Krishna consciousness is the art of spiritualising material activity, of increasing the degree of spiritual realisation of the doer, of knowing the universality of God and the relationship with Him.
To know one's intimate relationship with the Lord is the supreme goal of human life.
The true purpose of existence is to come to know God as He really is, to rediscover our true spiritual identity, to renew our bond with Him, to love Him, to link our desires and interests with His, to surrender to Him, and to return to our original abode in the absolute kingdom of the Lord, to serve Him with love and devotion and to live in His divine company for eternity.
We are all separate spiritual entities, eternal fragments of Krishna, God, the Supreme Person. We exist from all eternity as fragments, even after attaining spiritual liberation. But once liberated from matter, these minute eternal fragments of God live eternally with Him, the Supreme Person, and enjoy absolute knowledge and bliss in His company.
The Lord says: He who is unaffected by joys and sorrows, who remains serene and resolute in all circumstances, is worthy of liberation.
Whoever, firmly determined to realise his spiritual Self, is able to tolerate the onslaughts of misfortune as well as happiness, is ready to attain liberation, to be freed from matter. So it is with the order of renunciation [detachment from the things of this material world, disinterest in material pleasures, rejection of objects that arouse sense pleasure, and the natural rejection of materialism], which requires enormous sacrifices on the part of the one who adopts it, but no obstacle stops the human being who is truly desirous of making his life perfect.
The greatest difficulties come from the fact that it is imperative to break up family and social relationships, and thus to abandon the company of one's wife and children. But he who can tolerate this separation makes a rapid path to spiritual realisation. It is only with such strength and determination that one can free oneself from the bonds that hold one captive in the material world and return to one's original place in the kingdom of God.
