Meaning may differ from person to person. Mindfulness is a process to self awakening. We can call that a spiritual awakening. Blooming of consciousness is what we call awakening or enlightenment. When consciousness expands and opens into a new expression, we call that a spiritual awakening. May be awakening or enlightenment has its level. So, meaning of awakening varies from place to place and person to person. Example- a child starts to awaken to the nature of words and language. Someone suddenly knows that they are falling in love in their teenage or after teenage. How do they know this or what causes this awakening? More great is awakening of unconditional divine love. There are causes of the most profound spiritual awakenings, where consciousness suddenly recognizes its ultimate true nature. Self-inquiry, meditation, devotional practice cause an awakening (as told us by our Meditation Teacher). We can experiment with these processes and see what happens. It’s all about grace when Mind is awake and body is sleeping. Meditation practice is a part of the mystery of existence- Sleeping Body : Awake Mind.
