Ok here's my story about meditation expirience i had.
I did it for 6 months long time ago, i used to do it in the dark, sitting on the couch with eyes closed. I improved with every session that i did. Its very neat when u become without any thaughts. I had some struggles in the beginning, some sessions scared me. After 2 months of doing it every day i developed this tension in my forehead while meditating, it kinda hurts. But i still decided to go trough with it, and then it hit me BOOM the tension stopped and my pineal gland chakra opened. It was a nice ride, lots of neat stuff,my body felt light as a feather like floating, the white light that filled my head was spectacular, it felt like i was on the best drug, you feel absolutely wonderful, you cant describe the feeling with anything in this world. It takes a lot of patience. Im still not sure what to think of it all, it could all be imagionary, im not sure if it even benefits health.
