=== The Aura of a Yogi ===       The aura of a yogi is an indication of how much life force he has focused and accumulated, by way of extraction, from his environment into his body.       Upon the death of a yogi's body, this aura disperses back into the environment from which it was extracted. Hence, it could be said that a yogi has dispossessed the environment from some of its life force during that yogi's lifetime and the yogi allows the environment to repossess all of his life force upon his death.       What composes the environment of a yogi? All of the living creatures who exist within the biosphere of a yogi's environment including the Earth Spirit, Herself.       Hence, a yogi temporarily ''steals'' (borrows) energy, in the format of life force, from his environment until he is done using it upon his death.       And if a single, or several, devotees of this yogi are lucky enough to garner the attention of this accomplished yogi, then during that yogi's lifetime, all of these devotees will enjoy the benefit of that tremendous life force while the yogi is alive. This is called: the grace of the yogi, or in the Sanskrit it is rendered as: 'darshan'. Once that yogi passes away, all of that beneficial life force which each and every devotee of that yogi had enjoyed while their master was alive, will return to the yogi's environment and each of his devotees will suddenly become devoid of the 'grace of their master.'       If you wish, you may substitute the term of: 'parent' or 'teacher' in place of 'yogi' and replace: 'devotee' with 'child' or 'student'. They all amount to the same set of relationships.       I merely wish to point out how similar is our life by comparison to the lifespan of a 'free energy' circuit. It is not necessary to exclusively understand engineering without recourse to everyday commonplace experience if we truly understand our topic.
