Aging is the result of loss of prana from the body.
My question is.
Is it that with age the amount of prana produced by the body every month decreases ? or that the prana is consumed in removing the toxins accumulated with age, that little is left for the regenration of cells of body....that the body becomes weak.
1. "शीर्यते इति शरीरं " - "To constantly degrade is the attribute of the body". It is in the nature of the body, which is 'Asat' (unreal) to age and eventually fall apart. This process is at minimum intensity between birth and teenage. The degradation gains an upper hand from the onset of puberty [whereupon the vital energy (Veerya), which had been retained for optimal growth for more than a decade or so in the child, starts its downward journey, and gets expelled frequently, hastening 'Jara' (weakness & decay leading to ageing)]
2. A Yogi who has realized the significance of Brahmacharya, through 'Shama' (self control), 'Vichara' (inquiry), 'Vairagya' (dispassion) & 'Sadhana' (unbroken practice), strives to transmute the vital force, whose downward gates have been opened further to puberty, by sublimating it upwards. This gradually helps him break even the force of degradation of the body, and maintain its health, so as to effectively focus energies towards 'Atma Sadhana' (efforts towards self-realization, the purpose of the human birth)
The chief cause of ageing is the loss of 'Bindu' (seed of life), represented by Veerya (vital force), whose gross most form is Rethas (semen). Therefore, the practice of Brahmacharya is beneficial to maintain health & well being.
It is to be remembered that the body is an 'Upadhi' (medium) to work out karma, impermanent and unreal. One is not the body. Therefore, one should never be attached to the body. The aim should be to maintain health and well being [so as to effectively carry out Atma Sadhana, for ill health makes Sadhana difficult] and not get caught in the Maya of possessing physical beauty.
