Graining the ability to be grateful will diminish the desires that the separateness agreement can create on us. Gratitude helps to alleviate anger and greed. Abundance exists within the inside world. When your awareness is in the inside world you will live a life full of love, abundance, inner peace and happiness.
Pick one thing every day to be grateful for and before long it will become second nature to you. You could even go a step further and write them on a piece of paper and place them in a jar, then at the end of each week or month review them. This will eventually lead you to a life filled with gratitude.
