This is a video by Datta the youtube guru and there is something that caught my attention with this technique and it is that somehow it works on the crown chakra because i feel like something at the top of my head.
First Technique: You put your attention on your heart chakra and then you visualize a sun and a moon that merges with the sun and then you realize your thought.
Second Technique: You put your attention on your heart chakra ad then you visualize a tube of light that goes up passes throught your ajna chakra and then gets out of your head at a distance of about 12 inches above your head and it disapears and then you visualize a point of light in front of your heart chakra and then that light enter your nostrils and goes down into your heart chakra.
Is this heart chakra or crown meditation? what kind of meditation is this?
