Aspects of Shinto

I think there are 4 aspects in Shinto which is Japanese original religion.

1) Political religion - National Shinto
This is an aspect about Shinto which the governor of Japan use to govern the nation of Japan.
The Emperor was thought as the God and govern with the Shinto as the religious backbone.

2) Political religion - Old Shinto
This aspect is like the 1), but it are made by ordinary people, not by governor. "Tenri",
"Omoto", "Mahikari", and so on are famous religious organizations of old Shinto.

3) Spiritual aspect
There are a lot of spiritual being whose name are well known in Shinto.

4) Basical religion using "ki" energy.
I think there are no specific doctrine in Shinto religion, nor any books of scripture. It is
the simple system of using the spiritual energy. "Kiyoi = Good ki energy" and removing the
bad "ki" energy (="Kegare") are very important keyword in Shinto

I think 1) -3) has a lot of difficulties. But I think 4) is widely acceptable concept and
have possibilities to become the "Spiritual Platform".
