I think of it in a very broad way.
General protection, grounding, and strengthening along the path of inner development.
It helps to consider that different paradigms of spiritual practice would have different labels and understandings of the same phenomena.
What a traditional magick user might called spirit attack, a modern psychoanalyst might call neurosis or cathexis, a DSM-5 trained psychologist or psychiatrist might call a ‘psychotic break’, and a secular Buddhist practitioner might call the arising of unwholesome internal tendencies.
However we choose to label it, the underlying principle is that along the spiritual path we are exploring, questioning, and revising how our world is ‘written’. We’re messing about with the source code and seeking to evolve our paradigms. There are inherent and inevitable risks and perils of destabilization in such a project. You’re paving the road while at the same time you’re sometimes speeding down that same road at 160 kilometres per hour. Grandiosity and Ego-Blindness are only two of the milder risks along that journey.
Even with the best of intentions we tend to make the same kinds of mistakes again and again. Some end up associated with cults or cult-like organizations, or under the influence of a teacher who transforms into something not good. Or we may just unnecessarily blowtorch important parts of our lives because of the latest “insight we’ve finally understood”.
The perils of the choice to evolve. Not restricted to magick; not even restricted to conventionally-imagined “spirituality”. It’s part of any deep engagement with development.
I see Immortal’s Blade as a powerful set of protective guardrails as we find our ways along our various paths. The challenges may come from within or from without; and it’s good to know that you have a grounding resource to help keep you healthy and integrated as you go through your own metamorphoses.
So, in a nutshell, I think it would be useful for everyone. That’s one person’s opinion.
This’d probably be a good question for a support ticket, now that I think of it.
