Strength of intention is better compared to a laser-like commitment to accomplishing some particular aim.
This.
In his later books, debunked NewAge guru Carlos Castaneda made a big deal of word term 'intent'. I copypasta'd Google Gemini's answer here because his books became more and more abstruse over the years, and you really need some AI help to understand them at all - I don't know how his fans managed without it, I myself certainly didn't:
In the shamanic philosophy of Carlos Castaneda, "Intent" is an all-pervading, immeasurable, and indescribable cosmic force that is responsible for creating, sustaining, and transforming everything in the universe. Humans do not create intent; rather, they align with it. "Unbending intent" is the rigorous, fierce state of purpose and discipline a warrior develops to clean their rusty connection to this universal force and command it to alter perception or reality.
I think Castaneda was also an influence on Peter J. Carroll when he formulated his chaos sigil magic theory (you could probably also substitute 'intention' by 'will' here, same difference). In "Liber Null & Psychonaut" he writes about his own evocation methods:
[…] the will and perception are focused as intently as possible (by some gnostic method) on the elemental’s sigils or characteristics so that these take on a portion of the magician’s life force and begin autonomous existence. In the case of pre-existing beings, this operation serves to bind the entity to the magician’s will.
This intent focus is probably why he stressed the importance of empty-mind meditation so much - if you're able to gaze at a sigil for ten minutes straight or longer while exerting your will as a grim impersonal force devoid of any faltering or doubt, I think you've got it. The 'impersonal' part is crucial. It's not
YOU specifically doing something, it's the momentum of the universe that will accomplish things. It's hard to do though, which explains the popularity of the, ahem, 'lightning method' for charging sigils where you only have to focus your attention for a few seconds.
At least that's what Bardon meant who was also big on one-pointed concentration in his
IIH. It's mind magic, and apart from rock-solid concentration, you'll possible need good visualisation skills as well if you want to create entities, if that's what you mean. Haven't tried it myself though.
