The Vaasthu Shastra is full of ritualistic data that pertain to the relationship of a person to the earth (bhoomi) or with the energies (Vaasthu devta) or to the trees (Vana mahotsavam or Vana murhurtam).

The rituals in Vaastu are:

1) Vaasthu Muhurtham

After referring to the Panchangam or Indian calendar, the right time is chosen to inaugurate the site and to propitiate the energies. The time chosen is when the Vaasthu Purusha (energy grid) is awake and capable of participating in the ceremony in a powerful manner. Vaastu Purusha is awake during eight months- Mesha, Vrishabha, Kataka, Simha, Tula, Vrihchika, Makara, Kumbha) and asleep in the other four- Dhanur, Mina, Mithuna, Kanya)

2) Bhoomi Puja

This pooja is carried out at the same time as Vaasthu muhurtham. A small 64-part diagram denoting the manduka padam and the Vaasthu Purusha within it is marked in the NE part of the property using different seeds and colouring substances.

An effigy of the Vaasthu Purusha is made in straw and burnt to ward of evil spirits. This ritual is usually carried out in the morning.

3) Garbhanyasa

A ritual to bring alive the building and its spaces. Carried out in the evening or night after the building has been completed and is ready for occupation.

The ritual maybe carried out in the center or brahmasthana, or in the north, west, east, and south, on one side of the central axis.

4) Kumbhabhishekam

Rituals carried out for temples. After the temple structure has been completed, and the image of the Divine one (God) placed in the Sanctum or garbagriha, the Kalasam or bronze urn is placed on the top of the outer structure. Within holy water the Kalasam is finally cleaned.

5) Griha Pravesam

The final action of purifying and making ready the space for occupation in houses (residences) is called griha pravesam.

With all these rituals, the tradition has helped people understand the intrinsic and extra ordinary relationship they share with their physical and spiritual environment.
