The five basic elements in Feng Shui are described as metal, wood, water, fire and earth while Vasthu Sastra considers wood and metal as part of earth and includes the additional elements of ether and air. Both view the elements not as physical things but symbolising the cosmic energy.
The yin (darkness) and yang (brightness) are considered as the two kinds of energy in Feng Shui which tells about alignment with the earth’s geomagnetism.
North, in Vasthu Sastra, is indicated by a magnetic compass. Before the compass was invented, north was determined by using methods based on the position of the sun.
some of the salient features of Vasthu Sastra and Feng Shui are as below. Vasthu Sastra does not recommend the rearing of fish (in an aquarium or pond) while Feng Shui allows it. In Vasthu Sastra, it is sinful and inauspicious to have animals like rabbits, birds and hamsters caged in a house.
