Love is the principle of action, not a quality of behavior. We cannot learn unconditional love. To love unconditionally, we must become Love. And love is the natural outcome of union with the Inner Self or Soul.
Gratitude as a discipline involves a conscious choice. I can choose to be grateful even when my emotions and feelings are still steeped in hurt and resentment. Yet, the choice for gratitude rarely comes without some real effort. But each time I make it, the next choice is a little easier, a little freer, a little less self-conscious. Because every gift I acknowledge reveals another and another until, finally, even the most normal, obvious, and seemingly mundane event or encounter proves to be filled with grace. There is an Estonian proverb that says:
"Who does not thank for little
Will not thank for much."
Acts of gratitude make one grateful because, step by step, they reveal that all is grace.
