Every thing has two sides, like a coin has.
Like if we take jealousy for example…
If you come to look at it, every thing that you are jealous about are the things that you really like to have for yourself. So whenever we see them in the other and then we have a reaction where we compare ourselves with what we see and then the experience of lack generates jealousy…
But If one comes to think about it, anything that can make you jealous is actually giving you knowledge about what you don’t have but you like to have and if you are mind is running positively, then one can think about what one can do to get that thing or an attribute in oneself..
So, be as jealous as you can be but use the information rightly and bring change in what you do and you will have yourself an interesting road to success, to peacefulness, to joy, to fulfilment.
