The obligatory salah is basically a series of set movements that go with the words of prayer. However, it is not just as plain as it seems. It goes much deeper than that. It involves uniting body, mind and soul in the salah as the act of worship.
You have to ensure your mind is clear and in the right frame before you perform salah. You need to put aside all everyday thoughts and problems, so that your attention could be fully centered and exclusively to Allah.
Moreover, daily salah also could be an act to escape and relief from unpleasant everyday difficulties. You could take this very short time to recharge and motivate yourself before step into the harsh reality of life. May Allah give us His guidance.
