Dear PLJ,

  My father is 92 years old , has a fantastic memory and absolutely no ailments , does everything on his own, is absolutely cheery and has tremendous reserves of spirit . Wakes up at 4:00 or 4:30 AM every day never later even if a bit under the weather  , Goes to sleep by 8:00 PM (this is a recent development ) Otherwise never later than 9 to 9:30 at night . Why I write this is you have to understand something very clearly (as for me I am 50 years myself ) . If you lead a regulated life style and in the process have been leading a fairly decent life of moderation , there will be a sense of well being as you become older - not a sense of weakness . Faith and equivalent practices (nothing intensive - but leisurely done ) also confer a very happy life , the mind becomes cheerful and you can take it as a part of Dying , You enjoy dying .

god has given every person the ability to know the very changes in his mind and spirit . you are really lucky to be experiencing what you are at your age , there will be millions in this world who have everything on earth and yet would not probably be enjoying in mind and spirit what you feel (the lightness in steps, a feeling of going up,a soft effortlessness)

But these things do not come just to anyone , it only comes to people who have lived life in moderation and have live life maybe not as a wise man but as individuals with some practice of faith or other such stuff , but because of the intent being known by god , the rewards are there in old age , one lives dignified and happily , loses interest in the world and soon wisdom and yoga is upon him without any pain . You are ideally located now to really listen to your self amd monitor every single thing in your body . My father precisely yells me of the effect of different food on his mind and body and way of thinking , he eats what is agreeable to him , and has just a cup of hot milk at night or porridge as he says . I am not saying this by way of advice - I respect any person who has lived even One hour more than me in this miserable world .

My fathe sits happily in meditation , and like a small child or a cat wanders into naps and wakes up, I s happy if we sit by his side and we talk , is not unhappy if we do not . my mother passed away last year - for myself and my father  it was such an ennobling and intensely spiritual experience , words cannot describe some things - and so it should be also woth you - You mentioned that you are 70 it is very young , my father is 92 he has friends who are closing in on 100 and are older than him . I think that I have lost more friends than him at my age , at times I am ashamed when I think of it - I envy you - You are so ideally situated in life - you have nothing to run after not even knowledge , just let everything come to you

Of course there may be problems if you are living in places where there are an surfeit of physical activity in the open - 

this feelings of well being might get you gravitating to thoughts of youth and sex (I am being frank ) - much like those who take up Yoga and start to get some well being and then immediately have a surfeit of mojo all wrongly attributed to kundalini !!!- any man who starts a regulated life style will find that well being confers a sense of virility (also ladies) but it is this unseen creative energy that has to be dissipated into the spirit . It is god itself . It is not something from any organ in the body - it is from the surrounding space and it can literally lift a person physically and transport him .

Hope I have been helpful .You are quite young - the way I look at it (compared to my father ) . You should not need any knowledge anymore - just look very detached on the memories of the last 70 Years it will be revealing - the world is not required - your memories will give you whatever knowledge you require . I am not advocating anything you have to read this in the backdrop of the culture that I was born in . Just writing fearlessly at the cost of being misunderstood that is all.
