Given a choice, it is spirituality one should kind of attach himself to, not religion, for religion is divisive. You want to assert your religion and your identity. When people gather together and start talking they will side with their religions thinking that theirs is superior to the rest others. At times a heated discussion takes place and even violence is likely to erupt. Fanaticism, extremism, fundamentalism enfold them. Hitler and modern fundamentalists' staging is the repercussion of all this.
In fact, more or less all subscribe to the same role of God as a creator. All have similar attributes' of God as a savior, and yet there are striking differences when it comes to customers, methods of worships, and all these at times lead to clash and fight. For example in India both Hindus and Muslims choose Ayodhya as a sacred place for erecting their own dome, temple or mosque. There erupts a brutal fight for space.
Why this fight? This religious issue is all meaningless.
And if one believes in spirituality such frictions do not take place. All will respect the domain of one another and they will cord them by a common thread and there will be no divisive proclivity.
Spirituality is close to humanity.
