वास्तु मण्डन (मण्डन सूत्रधार - गृह, राजप्रासाद, दुर्ग एवं नगर-वास्तु सटीक)

Ch. I – Miśrakādhyāyaḥ 19
54-55. At the commencement of the construction of a house following
the science of prognostication the pole star is to be fixed first
of all. Then, on the right side or on the left side the Śānta will stay
in its own place. Śānta on the right side of the dog brings in fulfill-
ment. It is not favourable if on the left side and is regarded as
inauspicious if expanded/stretched or shaken.
56. If the construction of a house begins in an auspicious place,
the crows will caw sweetly. If in that place there are materials,
objects(Dravya) or splinters (Śalya) the crow will caw hoarsely.
57. With the effect of the principal omen a fort is erected, and with
its power a city and house is to be built, and it is for certain that
trade, agriculture and other types of occupations become fruitful
under its influence.
58. In the direction or quarter of the compass, at the end of the night
half of the Yāma and in the day up to half the Prahara in the
Eastern side are known as Jvalitā and others are likewise under
the influence of the Sun.
59-60. On the eight directions they are eight types, such as Dīpta
(bright) Śānta and others. The direction where the Sun rises is
known as Jvalitā and Dhūmitā on the forepart. Aṅgāra (fire),
Bhasma (ash), Vāta (air) and another four are regarded as
auspicious. If the sound comes from the left side, it is regarded
as auspicious in the Śānta (cool) work.
If the Southern direction is bright and the motion of the sound
en- ters from the left side then there will be concern for the
mongoose, goat, and peacock. The sight, narration and sound
will be totally beneficial for Kings.
