What's the "wallpaper" in your own mind?
Are you full to the rim?
Finish what is in your cup.
Once upon a time, a scholar came to visit a saint. After the scholar had been orating and propounding for a while, the saint proposed some tea. She slowly filled the scholar's cup: gradually the tea rose to the very brim and began spilling over onto the table, yet she kept pouring and pouring. The scholar burst out: "Stop! You can't add anything to something that's already full!" The saint set down the teapot and replied, "Exactly."
Whether it's the blankness of a canvas to an artist, the silence between the notes in music, bare dirt for a new garden, the not-knowing openness of a scientist exploring new hypotheses, an unused shelf in a closet or cupboard, or some open time in your schedule, you need space to act effectively, dance with your partners, and have room around your emotional reactions.
Yet most of us, me included, tend to stuff as much as possible into whatever room is available - room in closets, schedules, budgets, relationships, and even the mind itself.
