In feng shui, metal is the element you don’t often hear much discussion about. Most often metal is regarded as a cure for negative energies, especially earth afflictions such as the 5 Yellow and Black 2 that cause both illness and financial difficulties.
In feng shui every direction, such as north, south, or northeast has a number, color, element and a shape associated with it. Each shape has a distinct meaning. For instance, the tall, rectangular shape of wood is associated with growth. The shape associated with “big metal” or the northwest is round. This is also the shape of coins – or “change” – and wealth.
