Precept 7:

Do not lose yourself in dispersion and in your surroundings. Practice mindful breathing to come back to what is happening in the present moment. Be in touch with what is wondrous, refreshing, and healing both inside and around you. Plant seeds of joy, peace, and understanding in yourself in order to facilitate the work of transformation in the depths of your consciousness.
