Meditation is really about focus; focusing our mind on one thing, usually the breath.
Many times meditation is misunderstood as being just a time to close your eyes and relax. There is nothing wrong with this, but it is not meditation. The practice of meditation does require that you use the power of your mind to empty your mind and focus on the moment, not yesterday, not tomorrow, but right now.
This is more difficult than it sounds.
I have found that using special Brainwave Entrainment audios, the practice of focus becomes easier and that over time, I can achieve this focus without the audios if I choose to.
If you are having trouble getting into that focused, meditative state be sure to try a brainwave entrainment audio and just see how your meditation practice goes.
