What feng shui tools can I use to divert bad energy?

I share an office with an unpleasant co-worker, and it has created a very negative energy. What are some simple things I can do in my office to help?

We sit with our backs to each other (the only way the office can be arranged) and there is a dividing wall that our backs face. I have a window to my left (it is to the right of her). To my immediate right is a door into another office (a VERY pleasant office with good energy) and kitty-corner to that is the door to the hallway.

To improve harmony and auspicious chi within your work area, try using/placing a Tibetan Harmony Mandala near your work desk. Image of it here: http://www.smilingbamboo.com/prodbyviewd...

Additionally, you might want to check your auspicious/inauspicious directions which are dictated by your Kua number. That way, you can know whether to remedy or enhance a certain spot/direction you are facing: http://www.smilingbamboo.com/feng-shui-k...

Hope this info helps!

tape a mirror to inside of a drawer that faces her back..
Stick a line of red tape in the same drawer (color masking tape with a red marker).
Put a small bell on your desk and ring it when it gets to unpleasant. (it can just be a very tiny one so that you don't disturb others).
Try putting a plant on your desk, Tape a green triangle under your phone.
take a salt package and discreetly put it around your work area.
(salt repells negativity).
Obviously if anyone sees you doing this stuff they will react kinda oddly. But try to find a time when no one is around.
Good luck.
Blessings

I agree with the other answerer about a mirror - this will bounce back any negative energy and vibes back to your co-worker. Another discreet thing you could use would be a fairly good sized purple amethyst crystal - it could be used as a 'paper weight' but in effect is actually excellent for absorbing negativity. I would also recommend visualising a blue or purple wall of protection around you each day - this will only take a minute, and just do it first thing in the morning - it will be in place all day and I promise, it really works! Good luck.
