Then Shuk Muni asked, “How can one distinguish between a godly person and a demonic person?”
Shriji Mahãrãj replied, “In a godly person, vicious natures such as lust, anger, avarice, etc., are due to the influence of unfavourable circumstances. Under the influence of favourable circumstances, however, they are destroyed within a short time. But in a demonic person, vicious natures such as lust, anger, avarice, etc., are never destroyed. If someone were to speak some harsh words to a demonic person even once, he would not forget them for as long as he lives. Then, if that demonic person were to become a satsangi, he would initially appear to be better than all of the other devotees. But, he would be like the following: Silt that has gathered in the region of Bhãl – where there was previously sea – has made the soil fertile. As long as the silt remains, sweet water can be obtained by digging below; but if one were to dig much deeper, then extremely saline water would emerge. In the same way, even if a demonic person has become a devotee of God, the moment his wishes are not fulfilled and he is even slightly disturbed, then compared to the service of the sãdhus he had previously performed, he would malign them thousands of times more. Even then, his mind would not be content.”
