(252 The Vastu Deva; 253 Ascertaining of Vastu site for construction of buildings etc. ; 254 The Vastu Vidya; 255 The Vastu Vidya; 256 The Vastu Vidya; 257 The Vastu Vidya; 258 The measurements of limbs of the images of the Devas, etc. ; 259 The characteristics of the images of the Devas; 260 The forms of the images of the several Devas and their characteristics; 261 The forms of Gods, etc. ; 262 The pedestals on which the Gods are placed; 263 The dimensions of the Phallus; 264 The consecration of the idols; 265 Adhivasana Vidhise; 266 Installation of an image; 267 The bathing of the idol; 268 Propitiating the Vastu Deity; 269 The dimensions and related characteristics of temples; 270 The characteristics of Mandapas;)
