I find myself at times getting frustrated when I try anything. It is as though the candles or any other tool I am trying to use is "getting in my way" and ruining my concentration. In my experience, I usually work better without them. Not always, but usually. It is the focus, the meditation, the alertness of life around me, the energy from within that leads me to results the majority of the time.
It's almost like my choice of self-defense in the physical world... I have no clue how to properly hold, much less fire, a gun. I'm only good with a knife in the kitchen. My choice was a study of pressure points and of various kick-boxing moves, among other things. It freed me from having to carry anything, especially something that could be used against me, and in the meantime the nice people are not nervous at the thought of my carrying a weapon around. So it is with mindpower techniques, and why I prefer it the most. Even in one of my baby-food beginners Kabballah books, they talk about visualizing what you need so you can find it.
There have been exceptions, though. Some things I cannot explain (such as the dreams). I use the candles, the jars, etc if I think it can help energize me, and then I just try diet mountain dew or something... heh heh. Moon phases do not even seem to matter a lot of the time, it seems. It is as though when my brain is ready, it's ready. Waiting for a moon phase, or an eclipse, or a storm, or a drought, or a time of day just wastes my time and causes me too much confusion, and by then my energy and focus just is not there anymore. Either that or something else came up to demand my attention. I think there are better times to do things and even maximal times, like in the physical world where it is strongly recommended to water your garden and/or lawn either very early in the morning or very late in the afternoon/very early evening. Like I say all the time, though, I am always the student.
I've yapped enough. You get my point.

It's like walking down an empty street, listening to your own footsteps. But all you have to do is knock on any door and say, "If you'll let me in, I'll live the way you want me to live. And I'll think the way you want me to think." And all the blinds will go up, and all the doors will open, and you'll never feel lonely. Ever again.
