The enlightenment factor of tranquility, the calm serenity that begins to evolve out of the connection, interest and joy in seeing things more directly and clearly, brings a quieting of the disturbances of mind and body. Tranquility prepares the mind for deepening concentration, which is the 6th enlightenment factor. With a strengthening of moment-to-moment concentration, clarity and insight arise quite naturally.
Maintaining continuity of mindfulness in our moment-to-moment experience is a tightrope of continual re-balancing as life changes. Surrendering to this process strengthens wisdom and love.
