• Is it possible that my TF caused a kundalini awakening in another person? He is famous because He is a singer. We have not met physically yet, but I have gone through kundalini awakening and DNOTS and their ongoing. I have also had soul recognition so I know for sure that He is my Divine Counterpart and I do not have any doubts about it. But it is indeed perplexing that somebody had an awakening at the physical level because of Him. Is it a test for me? I have a mixture of feelings. On one hand I marvelled at Him and empathised with the person and on the other, I doubt if this just a test for me. I would appreciate your pov. Thank you for much.
