Hi, I created a very long post but apparently it didn't get posted on the feed so I'll keep it very short. I don't have any imagination, all I see when I close my eyes is black and all I can hear is my own voice. However, sometime when I practice (also the first time I ever practiced), I can see some greenish forms of light that come from each side and meet in the middle, forming a circle. I was watching the Step Three of Meditation video and I heard that imagination is essential for reaching Samadhi. Would my condition make it very hard / impossible for me to reach Samadhi and also do you have any knowledge / resources regarding my condition? Thanks a lot for the time and for any answer I may receive!
