Prayer is often used to refer to religious or spiritual conversation with a higher being. For Christians, this is the way to communicate with God. For those who follow other religions, it is the same thing – communicating with their own deities.
How to pray? You should simply open yourself up, your thoughts and your feelings, to the one you are praying to. It is a good idea to take the time to pray and find a place that is conducive to prayer. Find a quiet spot where you will not get easily distracted. Speak aloud or in your mind, offering your thanks, sharing your concerns, and asking your requests. The important thing is that you are sincere in doing so.
