Gratitude is the sweetest of all the practices for daily life and the most easily cultivated, requiring the least sacrifice for what is gained in return. It is a very powerful form of mindfulness practice, particularly for those who have depressive or self-defeating feelings, and those with a reactive personality who habitually notice everything that’s wrong in a situation.
Practicing mindfulness of gratitude consistently leads to a direct experience of being connected to life and the realization that there is a larger context in which your personal story is unfolding. Cultivating thankfulness for being part of life blossoms into a feeling of being blessed, not in the sense of winning the lottery, but in a more refined appreciation for the interdependent nature of life. It also elicits feelings of generosity, which create further joy. Gratitude can soften a heart that has become too guarded, and it builds the capacity for forgiveness, which creates the clarity of mind that is ideal for spiritual development.
