It was Moha (infatuation) of Dasharatha towards Kaikeyi, which was responsible for Rama being sent to the forest. Kaikeyi’s love for Rama exceeded her love towards her own son,Bharata. But, Manthara poisoned her mind. Consequently, she not only lost her husband, but also the respect of her own son. Today, no woman bears the name Kaikeyi, because she distanced herself from God. Similarly, no man bears the name Duryodhana, Ravana or Hiranyakashipu as they have lacked good qualities and developed hatred and enmity towards God. Hiranyakashipu was a great scientist. Ravana was the one who invented aeroplane. He had mastered the language of animals, birds and insects. But, people value purity of heart more than these achievements. It is the foremost duty of every individual to keep his/her senses under control. One can escape from the house on fire, but not from the senses, which are ignited by the fire of evil qualities. (SSS Vol.31, p. 397)
Can a man be called a human being, if he has qualities of devils, demons and beasts? Man is leading the life of a demon unaware of the path of truth, righteousness, peace and love. God has not created creatures such as devils and evil spirits. These are creations of man.
Krishna said to Arjuna, ‘Arjuna, I have never created demons and evil spirits. Then how can the non-existent demons appear in the forest? The demons you are referring to is not a demon at all. It is just a reflection of evil qualities within you such as hatred, anger, jealousy, etc. The anger is manifesting in the form of a demon, its power is increasing in proportion to the intensity of anger in you.’
The evil qualities of man are the real demons troubling him today. Man is under mistaken notion that demons exist and that they are responsible for his suffering. These are nothing but creation of his imagination and psychological fears. In fact, it is only man who has put another man to suffering. There are no demons and evil spirits in this creation.
