Einstein's postulation that it isn't philosophy but science that we would get what we desire by matching our internally-generated frequency with the frequency of the reality we hope for.
There is no higher frequency than divine Spirit, all that is of and from God. And for us, the highest frequency we could internally generate is that of profound gratitude.
It would be best, therefore, for us to already be grateful for what we want in order for it to manifest in our life.
