The buffer of time gives you the opportunity to get it right before it manifests, to take pleasure from the vision and from the molding it into place... Can you imagine if everything was manifesting instantly? You would manifest this, and then you would manifest it away. And then you'd manifest that, and then... It would be a difficult thing if you were instantly manifesting every whim or every misaligned thought. It's so much better that you have this buffer of time where you can feel it into perfection before it manifests into your experience.
