Immortality in terms of rendering aging obsolete is actually a rather simple concept, yet awfully challenging to master. It could be done in several different ways, in several different realms. In the physical realm the most efficient way would in biological genetics be by means of cyclic regeneration through wilfully controlled genetic regression. There are several different aspects which comes into play when considering this concept, but in essence, the functionality of the process mostly depends on one being able to biologically order it in conscious awareness. The general person are not even able to master the reflex of closing the eyes while sneezing, in the same way most are not able to master the cyclic regeneration. But at a certain degree of consciousness and awareness, in terms of internal perceptive comprehension, one are able to dictate the process of cyclic regeneration, and thus in extension achieve genetic regression. The greatest key to achieving this would easily be by means of discipline and understanding of animating self. One has to understand and treat every living cell of ones body like an individual with equal value and reason to exist; as this is part of understanding cyclic regeneration.
