The philosophical meaning of the word 'Satya' is "unchangeable", "that which has no distortion", "that which is beyond distinctions of time, space, and person", "that which pervades the universe in all its constancy." Human life progresses through different stages—from childhood to adolescence, from adolescence to youth, and youth to old age. It is through these changes that people progress in the manifest world. That is why human life or its receptacle, the body, is not Satya.
