When you become spiritual in your own experience of life, you can begin to see that religions are in fact political systems with a moral code for living based on a spiritual teaching. What is interesting with Islam is that it is the most encompassing of these aspects and is the reason why today it struggles so hard between the more fanatical political views the more moderate, because in effect all aspects are given account depending on the situation from which questions were being asked by the Prophet.
In this way, religions have been the political systems of the world until the industrial revolution which began to high light the economical experience of every human. It is from this that the modern political systems of communism, nationalism, liberalism and neo-liberalism (capitalism) have been born as each system has tried in some way to define the lives of the masses based on their financial experience of it as the religious teachings (as they were being interpreted and still are) did nothing to truly help those that were in most need of spiritual understanding (whether rich or poor)
With this has seen the separation of religion and politics as these new systems are not so much based on spiritual teachings to define the essence of decision making but the attempt to either balance economics based on fairness depending on what is perceived as fair. In effect the external (physical) experience of life has become more important than the spiritual experience of life. With that has come the focus on money and political power (through national identity) now dominating the decision making and a complete loss of personal power through personal accountability as the politicians seek to make all those decisions, in the way a religion did before based on the political system being followed rather than on the spiritual essence of the experience of life as promoted by religion.
This is not simply true in secular societies today, but also those societies that are still religious based as the populations are instructed to interpret the spiritual teachings according to the political needs of the region regarding money and power rather than to follow the spiritual path in which the spiritual teaching has primarily offered and was meant as a guiding light to political leadership. It is in this light today that religious organisations that aren’t in government also seek to gain power in the physical world, using a text in order to gain as many followers as possible with which to then influence the political landscape as well as the financial landscape
The money and power of religious organisations today is phenomenal, but not one is excising that power to its fullest extent in a spiritual way rather minor philanthropy is exulted to cover the disproportion that has occurred. It is for the spiritual essence of the followers who are living a spiritual life that make up for this short fall in the best way they know how with out good guidance as their intellectual independence is eroded from birth ensuring continued loyalty to the regional/cultural political religious system.
It is not wrong for the basis of politics to be spiritual in fact it is necessary to ensure that politics does not become competition over others, but a service to the masses. However the time as come to make spiritual teaching something that is separate from politics, and therefore religions as political systems, to ensure that as the generations evolve, those in positions to make decisions about the lives of others are fully equipped with the internal spiritual experience to guide them.
