Mindful self-forgiveness opens us to the truth of our situation, making it possible to learn from our mistakes and prevent them from reoccurring.
Being a practitioner of mindfulness without a system of ethics may help one relax, become more focused, or be less reactive in difficult situations, but much deeper benefits are available to us and to those around us when we begin to practice from a principled foundation.
Intention is the driver behind action and our ethics inform our intentions. Together these concepts are important because they orient us and point us in a certain direction. Aligning our mindfulness practice with our highest values helps us step out of the cycle of suffering and live with greater purpose.
