Compassion is the heart and soul and awakening to enlightenment. Meditation and self-reflection can make us more receptive to compassion, but it cannot be forced or manufactured. When it gushes within, it feels as though it suddenly came out of nowhere by chance. And it can vanish just as quickly. It is experienced in those moments when the barrier of self is lifted and the individual existence surrenders to the well-being of existence as a whole.
Thus, we cannot attain awakening for ourselves. We experience it by participating in the awakening of all life.
