Is the brush on the left or right side of the desk?

Whether the pen container is placed on the left or right side of the desk depends on personal habits and preferences. But from the perspective of geomantic omen, it is more appropriate to put the pen container on the left side of the desk, because the left side is considered as "auspicious position" and the right side is considered as "fierce position". Therefore, for good luck and auspiciousness, it is suggested to put the pen container on the left side of the desk.
