Incompleteness is due to incomplete Knowledge

All forms of incompleteness are experienced due to incomplete knowledge of the Complete Whole. The human form of life is a complete manifestation of the consciousness of the living being, and it is obtained after evolving through 8,400,000 species of life in the cycle of birth and death. If in this human life of full consciousness the living entity does not realize his completeness in relation to the Complete Whole, he loses the chance to realize his completeness and is again put into the evolutionary cycle by the law of material nature.
