Dear Pasha, Welcome to Bardon Praxis. >>>1.Whether is in IIH ways of protection and defogging equivalent on efficiency to rituals: "pentagram", "hexagram", "viewing tower "...? <<< Within IIH there really isn't much in the way of ritual working as you find within Golden Dawn, OTO and other such groups. Rather, Bardon presents a methodology which allows you to work with these energies directly, having a firm understanding of their quality and quantity before forming that understanding into a personalized ritual that is often quite a bit simpler than the rituals that you describe. The closest thing that you'll ever find to such a working would be the Magic of IHVH-ADNI that is the rough equivelent of the Middle Pillar exercise and so much more. You can find more information about this at http://www.tmo-wg.net >>>2.Whether has sense to practice Franz Bardon IIH to add exercises for development of the power centers (Chakr)??<<< Yes, IIH does include a methodology that helps clear out the bodies energetic system. One that tackles this job from the establishment of an elemental equilibrium within the self as well as the manipulation of vital energy. >>>3.Whether accumulation of vital force through breath by a leather {skin} of a body can, serve as protection against a magic attack??<<< Yes. Though I would also suggest that you check out the following page as well: http://www.abardoncompanion.com/Predators.html You'll be hard pressed to find an English translation of "The Practice of Magical Evocaton" online, though there are numerous German editions floating around out there. You can find an online copy of IIH and KTQ here though: http://bardon.freespeechsite.com/ I would caution you by restating what Bardon says within both PME and KTQ: these are advanced practices and should only be attempted once one has mastered IIH up to step 8. Though, they do give you a good idea as to what you should be aiming for, and the theory sections of both books are exceptional. Love and Live well, Peter Reist
