A longstanding issue I've been having which I think might be the primary reason I haven't had any success so far with magic, is that I'm really not sure how I'm supposed to be visualizing.
People will often say to visualize a specific thing, such as an image, a sound, a feeling, or any combination of senses, but I'm still unclear as to what that truly means.
I have some examples in the (admittedly crude, I apologize) illustration provided.
In figures 1 and 2, the pictured person is expected to visualize a triangle inside some sort of circular object on his wall.
In figure 1, he visualizes it in a way that's projected over his physical vision. He is seeing both the circular object as well as his visualization of the triangle at the same time using his eyes.
In figure 2, he visualizes the circular object with a triangle on it separately from his physical vision, instead in his mind's eye. He's not looking at the circular object physically, he may even close his eyes. He's instead viewing it similarly to recalling a memory of something he's seen.
In figures 3 and 4, the depicted person is expected to visualize a sensation in his hand. Perhaps a change in temperature, or the feeling of flowing energy.
In figure 3, the depicted person is visualizing the sensation as if it is physically occurring to him in the moment.
In figure 4, the depicted person is visualizing the sensation in his minds eye, again, similarly to recalling a memory. Perhaps he's even using an existing memory of a sensation similar to the one he is expected to visualize, such as a memory of touching a hot object.
The way I've always visualized things has been what's depicted in figures 2 and 4, but I've had occasions where I'm in a certain state of mind that allows me to visualize things similarly to figures 1 and 3, but these states were few and fleeting.
I don't know if there even is a "proper" way to visualize, but with my lack of any tangible progress thus far it seems it may be something holding me back. I'm approaching the "Big Three-Oh" with my virginity intact, and becoming a wizard is basically my only goal in life, so figuring this out is very important to me.
