Vastu knowledge passed by memory until it was written down in texts such as Samarangana Sutradhara, Mayamatam, the Skanda, Agni, Vayu and Garuda Puranas, Vishwakarma Prakash, Aparajita Prichha, Praman Manjari, Vastu Rajvallabh, Prasad Mandan, Vastu Mandan and Shilpa Ratna, each with its own focus.
In the Jain account, during the bhog bhoomi of the third era kalpavriksha trees granted every wish, until rising sin made them stop giving. Adi Prabhu then taught the six means of livelihood, asi, masi, krishi, vidya, vanijya and shilpa, and gave the complete knowledge of Vastu to his fourth son Vishwakarma.
In a house where any living being is killed or eaten, vastu never works. The teacher selects no place for wine, bars or meat and consults only after the family gives up meat and alcohol.
Sleep is an activity of Saturn; Saturn is a friend of Rahu-Ketu, who rule the South-West, and the South is the seat of Yama, so sleeping in the South-West or South is recommended, while sleeping in the East is not.
South-West or South
The water mantra chanted while pouring water into the pit is not found in Jinvani; it was to be shared with the class group (exact words: refer to the class recording), and the Gayatri Mantra can be used instead. The Bhoomi Jagran Mantra used for aahuti on the land is found in the book Pratishtha Parag, a text on pratishtha (consecration).
Adi Brahma (Adi Prabhu) gave each son a different knowledge: Bharat received arthashastra, Bahubali kaam neeti and Ayurveda, Vrishabhsen gandharva shastra (music and instruments), and Anant Vijay all the arts of painting, colour, brushwork and artefacts. Anant Vijay is therefore the source of interior knowledge, which he spread further, and Vishwakarma received the knowledge of vastu.
No place is selected for wine, a bar or meat. In a house where any living being is killed or eaten vastu does not work, so the family is first asked to give these up before a vastu visit.
Venus and Jupiter are never friends. Sleep belongs to Saturn and the comforts of the bedroom to Venus, so a Jupiter picture like this suits the bedroom only if you observe celibacy (brahmacharya) and restraint.
