Ch. I – Miśrakādhyāyaḥ 45 151. If the thread is torn or the pebbles of the measuring thread are displaced, then there is a chance of fear. If the peg faces down- wards, there may be disease, so one should take care in placing the nails. One should start work according to the eightfold procedure of con- struction . 152-153. Muñja is conducive to the auspicious look and cotton (Kārpāsa) leads to support. Wood is congenial for writing according to the eightfold procedure. Thus ends the discourse on pegs. 154. In a Vāstu, resting on Nāga, if the first digging is made on the tail, back or face it will cause fear. But if it is done on the left side of the womb it is regarded as auspicious and is known as Kukṣi. 155. If the Sun is on the three Zodiac signs of Leo and others and digging is done on that side where the Nāga faces, then it is auspicious and the digging is to be made serially from Vāyu (North-West), Maheśa (North-East), Agni (South-East), and Nairṛta(South-West). Thus ends the rules of Nāgavāstu. 156-157. To know about Śalya one should draw a chart of serpents with 28 chambers (Koṣṭha). There will be five slanting lines drawn upwardly with eight on the other side. Maghā will be on the lower part of the door frame and Kṛttikā will be on the centre of the door.
