Its a simple law of Universe. You create what you focus upon. If you focus upon darkness you provide strength to darkness but if you want to remove darkness you need to focus upon light. These days darkness is stressed so much. Every newspaper is full of darkness, all the TV channels are full of darkness. We feel strengthened when we see darkness in others. We feel we are better than what we see around us but we forget that we are strengthening darkness inside us while doing so. When I was doing my seminar, I went to a news paper to cover it so that a positive things can be sent to people and they said we cannot as people want to read only negative. We cannot give you space was their simple answer. If you want this darkness to go away from your life and around you, focus on love inside you and you will create love around you. Diwali signifies victory of good over evil. When you light a lamp it burns the negativity around you and that is the purpose of celebrating diwali. It burns the negativity around you and fill up your life with love, happiness and prosperity. However, if you do not understand and follow this simple thing, darkness would stay inside you. Often I have seen people making Diwali as an ego game and increasing darkness. Do not do this. Be thankful for whatever you have and whatever you can share. Real Diwali is in celebrating love and that definitely brings prosperity. Even Laxmi ji would not come if the place is dirty and that place is your heart. So clean up your heart to invite her.
