If anyone in here has not integrated the powerful technologies of vedic/daoist architecture into your sadhana, you are missing out on a lot.
I believe that good vaastu/feng shui is a great way to power one along the spiritual path. It helps alleviate karma through harmony with the natural laws.
Here are some great sources to get you started in this sacred art and science of architecture.

These should be enough to get anybody started.
