The devil, Maya, Ravana or Shaitan is most powerful in the present era called Kali-yug. The lust, anger, greed and ego are the most powerful weapons of the devil. Auxiliary firepower is provided by stress, worry, fear and frustration. Jealousy, hatred ad repulsion are the minor weapons for self-destruction. Self in reality is sukshma sharir, Atman or soul. Mind is one of the manifestations of the consciousness in Atman. Dr. Roger Sperry got Nobel for his concept of one brain two minds- Scientist Mind in the left dominant hemisphere and Spiritualist Mind in Right hemisphere. Today nothing is left in the left sphere and nothing is right in the right hemisphere. Indian sage talked about Antar mauna for self-realization. Sir Herbert Benson and Mind Body Medicine tell that inner silence of scientist mind gives the most powerful transcendental stage of mind which may progress to highest Turia stage of consciousness. The man then achieves super human powers [siddhis]like clairvoyance, levitation, astral travel and para-kaya-pravesh. BK-Rajayoga gives inner silence of Vikalpa, vicar, Vasana and Vikshepa[Devil's weapons] in few minutes. Most important achievement is that a quantum jump in the levels of Energy, Enthusiasm and Happiness[EEH value] by regular practice[Sadhana]till one's last breath. This happens because he waste of pranik energy through leakage and weight of negative thoughts and emotions on the atman are prevented. This silencing of tsunami in the mind, in turn, prevents the tsunamis in the physical world. Violent vibrations of negativity is in reality a tsunami in mind.
