The slope of the land has a big impact on the owner's life, according to the principles of Vastu. Land sloping towards the east and north is considered very auspicious, while land sloping towards the south and west is inauspicious. East directions always give continuous growth and prosperity, while a slope towards the north and northeast gives wealth. A slope towards the west and south may give financial and health losses, sudden death, and family disturbances.
Land that slopes towards the East, North, Northeast, and Southeast are considered auspicious in commercial Vastu. The highest point should be in the Southwest and the lowest in the Northeast. The Northwest should be higher than the Northeast, and lower than the Southeast. land that slopes towards the middle is considered inauspicious for both residential and commercial purposes.
There are four categories of land described in ancient literature: Gaja, Koorma, Daithya, and Naga Prishtha. These categories are based on elevations and slopes in different directions.
Transforming elevation on a piece of land can be done by transferring soil from one area to another. For example, if there is an elevation in the east, north, or northeast, the soil can be transferred toward the south, west, and southwest directions. If there are any slopes towards the southwest, they should be filled in immediately.
