OK besides of the Shiva mantras, specifically what would you use to activate your chakras? The bija mantras like LAM, VAM, RAM, et al. or some other exercise like visualizing color wheels, asking Satan repeatedly to activate your chakras, etc?
BTW, I've felt Satan gives a darker energy than Shiva; although in a trance I've seen him with the traditional red devil appeareance coming to me saying "Don't be scared, I'm Shiva". At least he's got the same healing power. But he came to me with a Gnostic way of seeing things. Maybe we can equate some Gnosticism with Hinduism, if we regard creator Brahma as the Demiurge; although Brahma's not seen as such an evil character.
