Jai Sri Baba Lal ji,
Know for sure that Life is a journey, it could be journey of animate and inanimate, and have different aspects and reality of this journey exists along with that hard to relate in mysticism of Maya,
Yet it is Very simple in case of living beings that behind the veils it is Atman that spirit which remains active and its activeness alone nourish the body, though an auto process with microns and miniature microbes, yet presence of spirit matters it,
As the spirit distant itself from, decay starts at the very moment, decay itself is transit reality that disintegrating the truth of body modules, and the process is inevitable in all cases of living being, irrespective of highly evolved human body,
It is human to regard this reality, though soul has only superficial power to relate the things in limited access yet behind this reality, spirituality support the soul varyingly to help in its sole motto of being human in journey of life,
Jai Baba Lal Dayal ji,
