Entrance padas & the Bṛhat Saṃhitā
The thirty-two doors, each with the text's reading and its verse, and the modern practice beside it.
Chapter 1
The Vāstu reference reads texts from the south (the Mayamata, the Mānasāra, the Kerala Manuṣyālaya Candrikā) and from the north and centre of the subcontinent (the Bṛhat Saṃhitā, the Viśvakarma Prakāśa, the Samarāṅgaṇa Sūtradhāra). Where they agree the pages say so, and where they disagree they say that too. Below is each treatise with the edition and translator a citation on these pages was checked against, because a verse number means nothing without the edition it counts in.
आपस् तथापवत्सः पर्जन्यो ऽग्निर् दितिश् च वर्गो ऽयम् । एवं कोणे कोणे पदिकाः स्युः पञ्च पञ्च सुराः ॥
āpas tathāpavatsaḥ parjanyo 'gnir ditiś ca vargo 'yam | evaṃ koṇe koṇe padikāḥ syuḥ pañca pañca surāḥ ||
