Sometimes we capitalize words. Like God. I guess it is to show that God is such an important dude that we can’t just throw his word in with all the peasant words.
We also capitalize ‘I’. Why would that be, do you think?
My proposal is this: let us uncapitalize the ‘i’ when we are referring to ourselves in the sense of the small self. And reintroduce ‘I’ when we are referring to ourselves in our capacity as God.
At the beginning of a sentence we will just have to be ambiguous because grammar.
