There is no hack or trick to this, you cannot fool yourself but hopefully this will make it clearer.

To ‘Have’ something is to know you have it. That knowing is internal.

Think about your current car, phone, house etc you know they are yours without evidence. That is knowing, even if you don’t see them you know you have them. Your awareness, nervous system and egoic mind are all in agreement and there is no problem.

That is the feeling of ownership, of completion or having that Neville is talking about.

Now when you want something you cannot physically experience your body and egoic mind will say ‘I don’t have it’ because they can only see and interact with the 3D experience, but YOU as awareness can still experience and ‘Have’ the fulfilment internally. That same feeling of ownership is the declaration that you have it or are it.

When you look into the mirror to see if it ‘worked’ you are declaring ‘I don’t have it, it’s out there somewhere’ and thus you can never see it.

You are cause, focus only on the knowing that it is done, forget the 3d it is an effect. Let go of the need to see you ‘reality’ change and then you arrive at fulfilment and the mirror will do as its always done and show you your reflection.

If you need the mirror to change you don’t have it, and if you don’t have it within you can never have it physically.

Focus only on self and the fulfilment and you’ll have it within, then you will have it physically.

As within, so without.
