We see that death need not be a necessary sequel to aging. Shedding off of the old cells keeps happening in a growing body too. So why does the body gradually become weaker and weaker? Here too we do not find any fixed and unvarying rule. There are people who age relatively early and deteriorate fast. Others retain their youth and vitality for a much longer period. Some simply drop dead in the prime of their youth, while others wither and fade away slowly. There are known instances in the life of certain yogis who have pushed death far beyond the norm of our species; still others have reversed the process, at least for the time being! What are the laws that govern this transition through life?
There is a tendency to pass off our ignorance under the huge umbrella of genes. While we cannot deny the role of genes in fixing much of our physical characteristics, we cannot equally deny the great role our thoughts, feelings, vitality and physical culture, as well as lifestyle and habits have on the aging process. Genes may lay the rough hardware, yet there is a flexibility provided within the species to alter the software we choose. There are people who indulge in every kind of excess yet seem to sail through smoothly enough. Others die soon despite clean living.
That our mind can radically influence matter is now well recognized in medicine, even though many physicians still choose to ignore this. Biofeedback, yoga-therapy and meditation are just some of the established means of influencing matter by releasing, focusing and chastening the energies of the mind. How far can we go this way? Can we alter the genetic sequence, mutate the genes, prolong life, retain youth, suppress the harmful elements, etc. etc.? Where are the limits? Perhaps as far as we believe them to be! Yet since all matter is one, and all life one in essence, perhaps the All-consciousness would not allow an indefinite lease to a species lest it disturb the total balance. Also the mind evolves out of life and matter and is therefore dependent on them for action and expression. That is why most of us cannot think clearly when febrile or with a disordered stomach. Even those who can liberate thought from the influence of matter, are bound to it the moment they begin to act upon it. A power greater than mind and freer than thought is needed to affect the most radical of changes — the material conquest over death.
