Moved to replie. What I have noticed is music, certain beats, and tones help me to
open my chakras up. Let's say it is in A minor, scale wise. Been so long since I've played my instruments. But when I would play a certain note I would feel the sensations.
Now it is more like instinct. They open when they want to, and I am constantly trying to keep them in check.
Word of warning. Do be careful to keep yourself grounded. When it lights up like a Christmas tree you feel undescribable. Read up on everything you can on it. I did all of them, and fell into a psychosis. I have psychosis now where as I haven't had it before. So I need some adjusting. I just want you to be careful. Try to contact someone locally who can guide you through it. So you can have an awesome experience.
Enough warning. Notes are keys. For me anyways. Along with your breathing. That is really important. Hope this helps.
Safe Journey
