We use words every day. All kinds of words in all kinds of ways.
But the magic to a word is the energy behind it. How you propel a word forward what emotions you put to it, is what gives it the power to hurt, heal, comfort, etc.
So the power is not in the word but what's behind it.
In prayer we give thanks, ask for help, pledge support or ask for intercession so that we can deal with a crisis/situation in our lives.
In this way prayer comes directly from the heart. Many believe they need to recite long prayers or remember prayers from childhood to pray correctly. Nothing could be further from the truth. We pray daily; even unknown to ourselves. We ask for strength, give ourselves a pep talk, or just encourage ourselves to get on and do something. These are beautiful prayers as they are about you, for you and have all the love in the world wrapped up in them.
Most people will say they are directed to 'pray' when they hit a bump in the road, when things are difficult and all is dark around them. They find themselves drawn to places of solitude, religion, or just get on their knees. They find they connect with the divine in these and many other ways and feel that their prayers as more profound as they experience the emotion and wrap it in their words when they pray.
You don't need to be in a dark place to pray, you don't need fancy words or long prayers to recite. You don't need to feel sad, you don't need to feel in any particular way to pray. Prayer is talking to God. Although it may involve asking for help and assistance too, it doesn't have to always be - you can talk to God each day and give thanks, ask for inspiration, ask for guidance, and anything else that you need. Remember that when it's from the heart and it is honest and true your prayers can be very powerful and you will find great peace and satisfaction in prayer.
