If the Comforter, Next Prophet or Kalki of Christians, Jews or Hindus has arrived on Earth, we must be able to prove the Truth. Yes, it may sound mind blowing, but we can feel it. As per Guru Siyag's Method of Meditation it can be experienced practically.
Just sit in a comfortable posture on ground with crossed legs, close eyes and concentrate on the forehead between the eyebrows, make a mental prayer that if that supramental force has arrived on Earth, I must get the Proof right now, If it is a truth, I must go into spiritual meditation for 15 minutes. Now keep concentrating on forehead and continuously chant any one sacred word of your choice(Jesus, god,Rama, Allah, Buddha, Krisna) in your mind without moving lips or tongue. Continue it for few mins and you will undergo automatic(Kundalini Controlled) spiritual meditation and Yoga body movements, hear or see Visualizations, Dont panic if your body moves, it will stop automatically after 15 mins.
