In a state of mindfulness we become aware of our thoughts and feelings and may choose to modify them. We are also in a position to enjoy the simple pleasures of being alive and awake. When we are mindful, we are cognizant of our perceptions. We are aware of sensations, surroundings, circumstances, and the flow and content of our thoughts. Mindfulness is remembering to be aware.
Mindfulness practice involves repeatedly bringing one's awareness back to the present.
Notice your thoughts without letting them carry away your awareness. Notice what is happening around you. Check your sensations. Notice your perceptions of touch, smell, sound, sight, taste. Notice the feelings in your body.
