Its good to be selfish and it takes a lot of effort to become selfish, where you think about yourself and you work upon self. Now to go truly selfish, first you have to understand the meaning of selfishness. Selfishness is not being mean, where you manipulate others for your motive. To understand self, first you have to start connecting with self. You have to understand what you are and why you are here. You have to understand whatever you are doing and why you have been doing that. Without understanding that you keep floating like a wooden log in the river. Once you understand self, you will make a boat of that log and you will be rowing that boat. Now the wooden log is not floating directionlessly in the river. It is a boat which is flowing. You will gain the direction. Once you understand self and take charge of the wood, you will know everything which is existing and is being created is one. There are different types and forms which are masquerading life. Every thing is created by existence is one. 2 siblings are born to one parent, you cannot deny their connection of blood and same DNA, so how can you deny the connection of everyone and everything around you in this existence which is created by existence. Every this is flowing with same consciousness but at different levels. When you understand the perplexity of the creation, you will understand that there is nothing which is not you. Every one is you and you are a part of everything. Once you accept everything as a part of you, you will attain the true feeling of self. The true feeling will take you to the feeling of oneness, where you will see everything and every being as a part of you and you will treat and love every being as you love yourself. Once you attain that, you will become trueself.
