omkara meditation

Many!! Anything from seeing past lives , to being able to heal my body to relaxing my mind..You see I had a stage three Anaplastic Astro Cytoma Brain Tumor , and I believe that along with the doctors procedures , and the healing of my mind , as well as others who do the same thing...Thats why I've been Cancer free for over two years..Even with with the doctors saying I only have two years to live..My sprit guide took me to the cosmo's , and showed me what it was like to be reborn to my mother that I have , and she knew it when it happen too..And she live 2000 mile from me...I have also been able to have the pleasure to experiance the "long tunnel with the white light and have the choice to proceed into the light or come back to the world as we know it..Another time I went to the mountains alone just to meditate , and had another out of body experiance..I was on a cliff about 2000ft vertical , when I found myself floating about a thousand yards from myself...Looking back at myself meditating , and being able to look down was pretty wicked too..I went alittle farther out , the decided that was far enough..And back I was..Much more went on when I was a child , I guess you can say I'm receptive to the other side , and the Masters want me to get it right this time so I dont have to come back to this hell ever again , and my spirit will be free to roam the universe , or where ever it feels it needs to roam.............
