I don't know if this will help, but I'm pretty practiced in meditations. Here's how I clear my head and meditate. I got it from a book and adapted it to make it virtually universal.
Take three deep breaths. With each breath, cast away any distracting thoughts, as though shedding skin.
Take seven more breaths. With each breath, imagine your chakras opening, a flood of light and energy pouring through them and throughout your body.
When you feel you're ready, open your mind's eye and focus on whatever you wish to achieve. This may be discovering aspects of yourself, communing with a deity, helping a friend, or cursing an enemy.
