Balance and Harmony
A few years ago, when it was just me and my youngest son, Amir, living together (we didn't have the dog yet, and Brownie was vacationing out of state), Amir gave me the other bear for Christmas, so I wouldn't be alone. Teddy has brought me a lot of luck, not to mention companionship.
According to the principles of feng shui, everything in a bedroom should be in pairs. So Brownie and Teddy sit up on the mantel, promoting balance and harmony in the household, discouraging isolation.
