Subtle but very significant relation is there between Religion and Politics. Just like the relation between you and your image. In modern times we have lost the ability to distinguish between the two, because politics has overpowered religion in the dark age.
Politics is mundane, politicians are supposed to be the servants of people but in fact they rule over us, whereas Religion is sacred, it's purpose is our spiritual growth, it asks for the inward journey, a journey within our subconscious where our Sanskaras(nature) are rooted, where we are in our true form with our true nature. Subconscious mind is the land where we are supposed to be at war with our self, so that we could recognize what actually we are , what is the purpose of life and how can we serve the humanity in better ways. Religion asks us to become the King of our own kingdom, where we live as an individual. That is our mind. One who is free from all desires is the real king.
On the contrary, politics is absolutely a different thing, politicians want us to see as the slaves, politics has been a curse, a calamity, and whatsoever is ugly in the world and in humanity, politics is responsible for. Political approach is exactly opposite to that of a religion. Religion makes us king, politics enslaves humanity. The best tool which fulfills the motives of politicians is religion itself.
There is no religion left on the earth, it has died. All what we are doing in the name of religion is that we are celebrating few festivals on the corpses of Krishna, Muhammad, Jesus and Nanak. We need to stop this drama. I bet if all religious places of all religions are demolished in the world, the first thing to disappear from the face of earth will be politics and politicians, and then only the True Religion would emerge out which will make us the master of our own kingdom.
