Step 2: Textual Examination
Although prominent Vastu texts such as Mayamata and Mānasāra address the significance of sound construction and the detrimental effects of imperfections, the Samarāngaṇasūtradhāra, authored by King Bhoja, stands out for its comprehensive and in-depth exploration of this topic. It extensively details how architectural deficiencies in buildings (residences, palaces) or urban planning can precipitate specific calamities, illnesses, financial ruin, and even the collapse of the ruler and his dominion.
