Jealousy from its roots
Jealousy is a feeling of resentment, suspicion, fear and intolerance against someone because of that person’s success. The one who has this bad habit is jealous. Some people took wrong meaning of it, for example a few days ago a very intelligent child lost his journal. He complained to the teacher about it and the teacher just told him to buy a new journal and do all the work again. The student became sad at this because he has to do a lot of work in the new journal. He just stood beside the teacher with a very sad look. Then suddenly he saw his journal in the pile kept in front of him. He told this to the teacher. But the teacher said that its somebody else’s journal and that his name was not written on that. The child showed his writing in other journals and asked the teacher to remove the sticker from its cover. The teacher removed that sticker and was very surprised to see his name on the journal. The boy became happy at getting his journal back while the boy who had done that was suspended for three days. This is called jealousy.
The other condition is that that if the dull boy wanted to succeed the intelligent one then he must have studied hard throughout the year and have achieved higher grades. This is not called jealousy, this is called competition. Try to succeed with fair means is competition.
So there is a fair line between jealousy and fair competition and one should be aware of the consequences of jealousy as the same person never succeeds in life.
