Well, I don't know if you can use runes to Open chakras, but you can empower chakras with runes, like Sowilo. You can use Thurisaz to unblock chakras and for healing. Thurisaz can also be used in black magic to destroy someone in a violent way. The Hagal rune is mostly used for black magic, so if your planning on doing some black magic, be careful. Hagal and Thurisaz is very powerful and it takes total focus and concentration and strong willpower to use these runes in any black magic working.
