To open your world to gratitude allows more beauty and delight into your life. We were all taught to say 'please' and 'thank you' as children but as adults we forget to say thank you for the simple pleasures in our lives every day.
Spirituality promotes the idea of gratitude in that allowing yourself to say thank you, you will create an automatic response where the universe will promote more occasions that please you. Making your life more positive and enjoyable.
Saying thank you to the things that please you, silently or out loud, helps you notice the grace in your life.
