Listening mindfully is a different type of listening than what we may hear with our ears. In fact our human sense of hearing is subjective and filters out much of what might be heard if we pay attention to the sounds around us.
Mindfulness involves, being aware of what is happening now, in the moment in four areas. First we are aware of our body, movements, sensations and posture. We listen to our breathing and to our hearts. The next aspect of mindfulness is to listen to and be aware of what we feel is pleasant and unpleasant. Being aware of feelings is important because it shows what we may be clinging to, judging or condemning. The third thing we listen to is our consciousness. We are aware of all of our mental states like anger or fear and their impermanent nature. The fourth aspect of mindfulness is awareness of the cosmic order and/or the Dharma, life and the true nature of our existence.
To listen mindfully is to be aware of our environment, our bodies and minds in the present moment. Being mindful in any of these areas brings clarity and balance to the mind. Being mindful is listening and being aware in the present moment.
