Prayer is not as hard or as arduous as many thinks. It's just simple communication with someone you love. This is the reason why it is very important to see God as someone you love. When you perceive God as such and you know and believe that God loves you back then communication becomes easier.
You can pray by talking, just normal talking, getting on your knees or while doing your household chores just simply pouring out your heart to God. This book as you know is downloadable which means you can use it anywhere and at any time.
