Given all the above Defenition for meditation is absolutely correct.And my small lines are
"Meditation transfroms A man from lower state to higher state in all Directions".Then only that meditator can get clarity in thinking, aware about all the situations going on.beyond that all the sensors will work perfectly in his body.throgh which he can get great knowledge from the other planets.
Get your own experience and conform about meditation is perfect which should know everybody in the universe.Then No need to write what enlightend masters told.
