Gratitude in practice

How do you apply gratitude in real practice? We hear personal development gurus talk about gratitude a lot. But what does it really mean? Is it enough to close our eyes and think about what we’re grateful for? What does it do? What actually happens when we do this apart from whatever effect it has on the universe which, whilst I do believe in, does not offer tangible outcomes, internal or external that we can attribute to it.  For me the keyword has been replacing the word ‘thinking’ with ‘feeling’.  This simple practice made my life many folds better. I hope it does the same for you.
