I remember in Mallorca MMY had us take 3 days of silence with limited food intake, we'd stay in our rooms for 3 days rounding. And then in the Fuiggi Fonte Theatre he said: "You could meditate a million years and not reach CC unless you come to these courses", well that ended any speculation about reaching it in 5 to 8 years.
So,you know this idea that TM'ers are reaching Samadhi in their regular meditations 2X20 is just theory pertaining to the bubble diagram, 'some day' you will actually transcend relativity and that experience will be so profound it will change your life forever. This idea that I transcended and forgot the experience is not Samadhi, Samadhi is something you'll NEVER forget! A faint awareness of Being (though good) is not the same as transcending the entire field of relativity; the physical, astral, and causal. Through the spinal chakras I might add, as MMY has said, "the chakras are the milestones on the path of kundalini", and kundalini leads to Samadhi there is NO other way or path, that's the way the human physiology is hardwired...deal with it! http://alex.natel.net/ffl/audio/MMY/ or http://alex.natel.net/ffl/audio/
