I am going to start a Sun Square for specific goal soon, and I want to know, is it OK if I boost the square with Runic magick, and maybe even simple Raise-Program-Directed energy like after the RAUM meditation?

It feels to me that a square is just several minutes a day of vibration, and despite their astrological power, that's not very much time spent directing energy toward my goal. Am I able to boost the power if I spend more time throwing energy at the same goal?

I know squares are very sensitive, so I ask, can it be enhanced by other magick workings with the same affirmation?

Definitely. I do that at any time if possible to match both timings. I make the affirmation slightly different just in case.

Yes you can. I experimented doing this.

Just do not doubt that your workings are helping the square, and it will work.

I did the same affirmation and everything as for my square, in a daily energy working after my morning routine, and I still got results. The square was not ruined.
