Working With Sulphur
To do anything in inner alchemy you first need probably the most basic skill of mage craft: The ability to pay attention.
Attention is a thing. It is not just something you do. Children act out for it, friends and lovers crave it. It is a currency, a commodity. The ability to pay attention is also a good sign you have a strong Sulphur, a strong consciousness. You know your Sulphur is weak if you are always foggy headed, or weak willed.
Sulphur is the connection between your Will and your Mind, and if it is weak you will have much trouble coordinating the two.
The best way to keep your attention strong is by using it. This is boring. This is, in fact, very boring. Drifting off in my head is one of the first things I learned to do in school.. Because it was so terribly boring sometimes.
There is hope though, because paying attention is not thinking. So if you are sitting there, driving to work with the radio off, paying attention to the simple act of driving (something I highly recommend) and you start to think, "Did I leave the door unlocked?" or "God, I wish traffic would just GO!" or any of those, pause for a second, and just go back to paying attention to the flow of traffic, to your body doing its driving thing, and the scenery passing by.
Do this with ordinary things. Do this every day. Ordinary things keep it boring. Boring is good. Boring means you are butting up against resistance, and thus strengthening your Will. Anyone can pay attention to TV for an hour.. something new and shiny and distracting every moment. It literally drains away your attention.
Pay attention to people you talk to, especially at work, but hell, anywhere. When you focus your attention on someone, something in them notices, and thus they will usually give back a bit of the attention they used just as a matter of unconscious course.
It's not going to be easy. Your mind is going to rebel, but keep going and with enough practice you'll have a good strong sulphur, one of the best, simplest tools in your arsenal. Our sulphur, the very force of our Will and attention is going to be the flame that heats our Matter, and allows us greater access to, and greater abundance of, our vital force.
