It reminded me of one of the most surprising experiences in my life. In the years following my initial awakening, I did did the heart prayer and Christ meditations and visualizations along with a more Buddhist practice, and along with everything else happening, I noticed an unusually intense activity on the crown on my head. The awakening also allowed me to see energies, and as I happened to walk past a mirror following an especially alive Christ meditation, I saw a flame on top of my head.
It was hugely surprising to me as it seemed to reflect the descriptions in Acts, which I up until then had taken as purely metaphorical. Now, it seemed that it was far more than metaphorical. The tongues of fire is a literal description of what happens when we connect with the Christ consciousness and energy. There are literally tongues of fire, energetically, activated at the top of our heads, and visible in our energy systems.
I am also surprised by drawings and paintings such as the one above. It is just about exactly what I saw, and see whenever I immerse myself in Christ practices. Have these artists seen it for themselves? Do they intuit or sense it? Do they base it one representations made by others who have seen it? It is probably a combination, and different for each artist. But it is still surprising, and beautiful.
