There are mystical schools where they teach meditation without any secrets, only needed delivery, knowledge of the existence of further evolution worlds, there is nothing mysterious, only four principles: No analysis: some schools teach that meditation is not thought, but, is not necessary to abolish thought and even is a loss of time trying to eliminate thought since this is inherent to the functioning of the brain and the physical body. It is something like the waves of the sea, in the evolution are interested in delving into the sea, the sea has higher content of water inside that on the shore, if we focus on eliminating the waves to be able to penetrate into the ocean, probably someday we achieve it, but we lost so much time that we had already known much of the sea. No analysis, means they should not concern us thoughts, if it appears a thought of something that we did during the day not have to ask us because we did not do otherwise, if it appears a thought of Red will not investigate because it is not simply blue, thoughts are there because they are part of a functioning brain or human naturalnessWe must not look at them, what interests us is to go much more beyond of the mind physical, beyond the physical analysis, to enter the world of wisdom, regardless of simple waves of crude thought. Do not want: when someone want to, travels to the past or to the future, one would have liked that things in the past had been developed otherwise, willing to change the facts, also the future is to this or that way, wandering between the past and the future. However, the past is not currently true, It was truth at some point, but there is no more. The future may be true at some point, currently nor truth.
