Good Feng Shui means you have a balance of the five elements that compose the earth. The five elements complement each other in a form of life cycle.
The ideal system is where water produces wood, wood yields fire, and fire fashions the earth. Then, the earth forms the metal and the metal consequently produces the water. The overbearing and ugly system is when the elements contradict each other: wood burdens earth, fire destroys metal, earth hampers water, or water kills the fire.
You don’t have to be a geologist to understand good Feng Shui for earth. Lacking in earth, you may find yourself filled with instability and resilience that the earth is generally known for.
Electronic devices can actually have good feng shui as well. Make sure that metal is not colliding with fire elements, and this may even hold a practical significance because you wouldn’t want any of your electronic devices to catch fire!
Zen fountains and the like form the water aspect of Feng Shui. Just ensure that water complements your metal. Overpowering your home with electronic appliances may actually appeal to the gadget junkie but not to the Feng Shui aficionado.
Candles and fireplaces are good examples of fire elements in Feng Shui. In business settings, it may also be advisable to tame down the effects of fire in the office. But it can be more unleashed in the personal setting, especially in romantic ones.
Wood is abundant in many places. Just by cultivating a garden in your home, you will be able to bring in a lot of wood that can help you balance the different elements.
