I noticed if you do a breathing exercise after Opening the Watchtowers (Right now particularly the 6th chakras) that it gives enormous amounts of energy to your chakras on your head. Particularly the ones you work with during the watchtowers. Even one time I was able to see a tiny spiral of energy floating as soon as my vision was regained normally for a second.
But just be careful doing this because I fell twice doing the breathing exercise because my legs start to tremble and my vision fades to a purple. Perhaps sit down in a easy pose while doing it.
Other than that, nothing feels more empowered right now than the chakras i just worked on.
I kind of wonder how it will be when I do it with the heart & so forth. Really excited to do so soon too.
