It doesn't have to be complicated.
The steps you go through initially don't have to be taken every time. At first they are there just to walk you through, so you know what it feels like. Your body/mind will learn how to do an action more efficiently every time you perform it. After a while it becomes natural.
When I'm about to enter state, I just just inhale as I state my purpose, then relax as I open my eyes. I'm good to go.
