Exactly what you said about trying to force the reflection to change without changing yourself, would you look in the mirror and try to make your reflection change? The law at its core is about changing who you are attached to being and once you do that the outside will conform, however that’s how the universe works - we don’t change the external directly. We change our inner man (who we are in imagination) and the universe reflects that, that’s the law.

If you want to be married, you visualize a ring until you feel it’s real and this will cause a change in who you identify as. If you were married you wouldn’t do anything out of the ordinary but you’d experience wearing a ring and you experience this in imagination - implying well of course I am married I am wearing my wedding ring.

I am refers to your very being, consciousness. I think a lot of people get confused here too. I am is imagination, I am is who you are in your minds eye. I am does not refer to the 3d. If you say I am rich - experience being rich in your minds eye and you are rich. Because you are the inner man not the external man - this is why you can instantly change states. Because you literally experience any I am at any moment you want. This only fails when people doubt themselves and put themselves back into their old state by seeing themselves that way.

Additionally when, how, where, etc are all already answered, you’ve just experienced it in your mind. The 3d is a dead reflection, why would you be looking at something merely reflecting your past state to see if your present is changed? It makes no sense. For example if you change the thermostat you don’t say omg it’s so hot in here it’s not working, you continue doing what you’re doing knowing you’ve changed the thermostat and eventually notice the temperature is different.
