The Little purple notebook, "How to Escape from the Universe", shows how, but why?
"Gotamo Siddharto, a local Prince in India 2,500 years ago, after going through most of the many spiritual and physical exercises that were taught at his time, decided to try a radically different approach and eventually succeeded in waking up from the dream of life to a state beyond this Universe.
Gotamo asserted a 'state' that is fundamentally independent of the system of this Universe. Since labels can only be attached to phenomena that are within a system, there cannot possibly be a name for this state and even classifying it as a 'state' is therefore, strictly seen, incorrect. Likewise, whoever is able to reach this 'state', cannot be labelled either.
The only possible approach to this 'state' is an _indirect way_. Therefore, Gotamo taught a way of thinking in exclusive terms rather than the common way of thinking in identities.
For example, contemplating 'self' is necessarily an identifying and self-reflexive way of thinking and it cannot possibly lead to the 'way out'. In the contrary, since thinking in identities is the very condition that is holding Beings in this Universe in the first place, self-reflexive thinking will INCREASE the bonds that prevent a person from being able to have the choice of withdrawing from this world.
