When a new house is built, people often find it difficult to decide in which direction the foundation should be laid. Some people always recommend starting the foundation from the *Ishaan* (north-east) corner, while others suggest the *Agni* (south-east) corner. However, it is important to understand that the correct direction of laying a foundation is not fixed; It keeps changing. The specific direction from which the foundation should be laid depends on the transit of the Sun (*Surya Gochar*)—that is, its movement through the zodiac.
According to Vastu Shastra, the snake is deeply connected to the earth’s energy and *Kundalini* Shakti. The snake is considered a symbol of *Kundalini* Shakti—the dormant spiritual energy that resides within the human body. Furthermore, the earth itself is considered to be the abode of snakes (*Nagas*). It is believed that the position of the serpent—specifically the direction of its head and tail—which supports the Earth, changes according to the transit of the Sun. As a result, laying the foundation of a house in a specific direction where the head or tail of the serpent is located at that time can prove disastrous. Doing this has often been seen to bring some kind of misfortune or calamity.
The relationship between the Sun and the foundation of the house
1. When the Sun transits through the signs Leo (*Simha*), Virgo (*Kanya*) and Libra (*Tula*), the head of the serpent is believed to be located in the *Ishaan* (north-east) corner, while its tail is in the *Nairiutya* (south-west) corner. During this period, it is considered auspicious to start laying the foundation from the south-east direction.
2. During the transit of the Sun through the signs Scorpio (*Vrishchik*), Sagittarius (*Dhanu*) and Capricorn (*Makar*), the head of the Serpent is situated in the north-west and its tail is situated in the south-east direction. At this time, it is considered auspicious to start laying the foundation from the north-east (*Ishaan*) corner. 3. When the Sun transits in Aquarius, Pisces and Aries, the head of the serpent is situated in the south-west direction and its tail is situated in the north-east direction. During this period, laying the foundation from the north-west direction is considered auspicious.
4. When the Sun transits in Taurus, Gemini and Cancer, the head of the Serpent is situated in the south-east direction and its tail is situated in the north-west direction. At this time, laying the foundation from the south-west direction is considered auspicious.
Adverse effects of laying foundation on the head or tail of a snake
According to Vastu Shastra, if the foundation of a house is laid from the specific direction where the head of the serpent is located, it has been observed to have serious consequences—including incidents of death in the house. Therefore, the foundation should never be laid from the end that corresponds to the head of the serpent. Minor complications arise when laying the foundation from the tail end. Conversely, if the foundation is laid from the center of the serpent—or the center of the house—construction stops midway. Apart from this, one should never start laying the foundation or start any construction work of the house on Tuesday.
