To obtain the Elixir of Life
Know first, that none lives for longer than his span, save by the
permission of God. And therefore sages have written that this must
be asked of God, before the water of life can be made. Alexander
found the fountain and when he saw it, he was afraid, for the first
time in his life, because he knew that there was much danger and
fear therefrom. Therefore, if you are not afraid, prepare yourself
with fasting and meditation for the space of forty days, and then
when you are fortified, go out into the desert and seek a stone
which is blue on one side and red on the other. This abounds in the
deserts of Africa, and it is known when it is seen, for there is no
other stone like it, and the two colours are separated by a white
line. This is a stone, and it is not a stone; and those with wit will
know.
When you have found this stone, you must take it to a place far from the world of men, and there you must make for it a sheath, which is of copper and gold, and mount it therein, with the figure of a bird inscribed on it, and the words LI LI LI NA NA AN (This could be "لي لي لي نا نا ان" The book is translated from unknown language into english including the talisman so i am not sure whether it is arabic or hebrew.). Then you place it in water which you have brought from a running stream, and leave it there, alone and buried for the time during which seven moons wax and wane. And then, taking with you new clothes, and having bathed and eaten nothing, repair to that place.When you have the stone in your hand, say the words again and again, and place it on your heart. When this is finished, put off all your clothes, and make a fire from them. Then take up
the new garments, and robe yourself. If they are green and white, it is ltetter. Then take the water that has been with the stone, and it is the 'Water of Life. Half of it is to be placed in a small container, and this is to be stoppered and carried with you. The other half is to be drunk, when the sun comes up. Then you will live for the period for which you have prayed to be spared. But there is a strange thing about this. I have heard it said that every person who takes of the water of life longs for death in the end, and that beyond two hundred years he cannot live. So he must take the remainder of the water, and drink that, and he will then die at the appointed time.
In arabic magick there is this kind of practice for longetivity by reciting few prayers every day. By the way, i heard that if you want to avoid sickness you should stop breathing because the air nowadays has been infected by chemical and acid, that's why alot of people getting sick because of breathing especially because of smokes. According to some information people before chemical and acid was created can live more than 200 years, as example is the old prophet (Peace be upon them all.) Well i might be right and i might be wrong, Have a nice day!
