I think when somebody meditates if he sees light emanating from his heart, he is considered as spiritually enlightened person. The color of the light he sees (e.g violet,blue...red) determines his spiritual rank(violet means low...red means high). If somebody closes his eye and just sees darkness he is not considered as spiritually enlightened. I saw few posts about people practicing Yoga ,meditation, and people getting freed by their God etc. Now my question is have you been spiritually enlightened yet , If yes what color of light do you see
