He incarnates to lead man to the right path. Man at the time of birth is absolutely pure and sacred, but as he grows up, he loses his human values due to his excessive desires and association with worldly relations. The sacredness of human birth is so great that even gods would salute him. Today human values are becoming extinct. Man should continue to be as pure as he was at the time of his birth.
Excessive desires are responsible for the decline of human values in man.
Having been born as a human being, you should practice human values. Body is meant for practicing Dharma. But man forgets Dharma and indulges in selfish acts. None can escape the consequences of his actions. O man, do not build castles in the air.
