Kundalini shakti. Its the higher self. You can use the light waves to create telepathic thoughtforms. Telepathy isn't just about communicating with people, but also about extra sensory perception and sending thoughts outside your brain cavity. Next time you see the blue light, imagine a familiar location, and the light should shift into resonance with that location and you will be able to remote view.
