Yes that seems correct lapis about using numbers in very different ways than what our conscious minds are aware of.

As for 412 I've noticed that when I feel frightened and use it it gets rid of that fear and the feelings that led to it.

As for the realm of sacred geometric shapes and blue prints I wouldn't be surprised at this. The way I see things, everything is affected by a number-a lot of things we aren't aware of but numbes are something we encounter every single day-not just door or bus numbers but we see things in numbers, ie: the number of say brown dogs that we see on a particular day.

I will start to pay more attention to numbers-there is certainly more to numbers than just quantifying!
