Frequencies:

One time, when I was chanting chakra mantras aloud, I heard their corresponding frequency vibrating off of my teeth. Sounded just like these videos.
.
Which direction I think the chakras spin:
Counter clockwise. I use the right-hand rule. E.G Point at your chest with your right hand’s thumb. See what direction your other fingers are going? That’s the way I feel the chakras should be spinning.
.
Rocks:
Certain rocks help certain chakras out. Googling “chakra crystals” should give you lots of info. I don’t know much about this except that tucking my lucky jade charm into my bra was the best thing that ever happened to my heart chakra.
.
Herbal fragrances:
I heard that certain incenses or burning herbs help certain chakras out, but I can’t test it out. I don’t own any herbs and Mom wouldn’t appreciate me burning anything in the apartment.
.
What good is meditating on the chakras:
Besides the reasons under Basic, meditating helps with concentration, with awareness, and clear thinking. Meditating on the chakras makes things more interesting by giving you a goal and something to visualize, while meditating.
