GRATITUDE is a choice that becomes a habit. It is a major ingredient in the alchemy of transformation and is closely related to love... Gratitude creates a combustion of energy that powers our living cells. That's why all spiritual traditions teach the importance of gratitude. It certainly isn't because the deity needs any reassurance. Rather it's because when we are in the state of gratitude, we're affirming our faith in our own highest good and denying authority to the paralyzing, constricting energy of fear.
Mindfulness is an ancient form of meditation in which one pays attention to the present moment and all that's unfolding in that moment, both within and around one. It's known also as conscious living because the person practicing it is forming an aware and intimate relationship with each moment.
When practicing mindful meditation we aren't striving to do anything, we aren't grasping, struggling, thinking, expecting, or wanting but simply letting whatever is there be there and paying attention to it in a non-judgmental way. We come to terms with reality as it is, bringing all our awareness to it, breathing with it, attending it.
