I have a constantly raised Kundalini all the way up to crown chakra and including my feet and hands (my entire physical body is full of energy except for my hairs), I cannot turn it off, she is with me all the time, I never done Yoga or meditation in my entire life and I was never religious in any way whatsoever (I believe you dont have to believe in God to have Kundalini, either everything is God or nothing is God, either way it is the truth). I hear voices coming from my chakras and I can communicate with them quite effectively they sound like bees, birds, snakes and a cat purring near my genital region, I am spending a lot of time trying to decipher their language and at this moment in time I can get simple "yes or no" answers and know their reactions to good or bad thoughts.
I have had telepathic experiences, done telekenises, I am able to Astral Project/OBE, Remote Viewing, I have even had a mass telepathic experience where I was hearing millions of voices at the same time, some of them human, most of them sounded alien (imagine if a tree had a voice, thats is what it reminded me off, very natural), I called this phenomenom Anima Mundi (Living Earth) or Great Mother. I have also travelled to my cellular level in my body, looks exactly as seeing my body through a microscope.
By the way it is impossible to have ommniscience while in a human body, there are not enough neurons in the brain to store an infinite ammount of information. You can only do that via your spirit body, I had a glimpse of it while I had my mass telepathy experience. But integrating that experience when you come back is incredibly hard (maybe not impossible but you will deffinetly be locked up in a psychiatric ward) and I went through years of psychosis/schizophrenia after that experience. Anyone who thinks they are ommniscient are ingorant of the fact that the universe is infite and just because you have seen 1 more piece of the great puzzle does not mean you see the entire picture. If you knew the truth you would know the universe is greater than all the galaxies put together, they are not even 1% of the picture.
In my honest opinion, EVERYONE HAS KUNDALINI, they are just not aware of it, to prove this I will tell you another experience, I was looking at my best friend one day and he turned black, and I saw orbs of glowing colour all the way up his spine (Chakras?). He has never told me anything about the chakras or kundalini, and as far as I know he is not aware of them.
By the way, Ommiscience and Free will are mutually exclusive, if you were Omniscient you would lose free will since if you know everything that is going to happen the choice has already been made, that is the reason I believe you cannot have ommniscience while being Human, you can only do that by escaping from Samsara (The cycle of life, sickness, death and rebirth as described by the buddhists.)and rejoin the source of all things.
