Go to the top of a mountain. Does your eyes see more than what they see when we are on the ground? Same eyes . Same world and yet what limits the vision of the eyes. The eyes do not limit it. What does?
It is the obstruction in the path of of our vision that curtails the full capability of the vision of the eyes.
As you go up to the top of the mountain you are the same. Your eyes are the same. But the obstructions have been left below and you get a panoramic view of the place. The key words are … higher plane … panoramic view..obstruction.

Apply these to the mind. Simply apply them.The mind will go far far beyond the limitation. It can expand beyond comprehension. It can go deep inside. It has lightning speed. It can crawl to a standstill. This is the mind machine.
I am sure you have read about people with tremendous mind power. Just by intensely looking a metal rod they can bend it!

Mind has got immense power. Sky is the limit. It has no limitation, restriction or condition.

Mind of course is a mysterious power. Mind as flesh or matter can be probed by doctors. But the mind as a spiritual power can only be unfolded by individual self. If one wants to achieve absolute power of the mind, he should first of all forget his ‘ego’ and egocentric desires. His heart should be pure. Heart here means his feelings. He should be self-less and have sacrificial tendency. The intention should be superb and the motive should not be ulterior while discussing about mind.

One should not play with the power of the mind. It is like electrical power we can say. If we play without proper discipline, it will give contrary results. I mean one may become mad. Mind is equated to Moon. A mentally imbalanced man is called lunatic because of this reason. Mind should be crystal clear like a moon. It should be cool. We all hear the word cool minded.

Further details can be had from your local Yoga Teacher.

G Open to the ninth level of consciousness. That level is unlimited and indescribable and can be opened to by anyone willing to drop their preconceptions and addiction to limitation.
Before Daisaku Ikeda got into the ninth-level path, he was a sickly nineteen year old with a limited future but strong thirst for learning. Now he is head of a 12 million member organization in 192 countries, has over 240 honorary doctor degrees and honorary professorships from serious universities like Oxford. He lives without fear or regret and is a vigorous eighty year old helping millions toward ultimate mind power. It is worth noting that this is done without fees.
