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

Ch. II – Āyādhikāraḥ 71
43. If Āya and Vyaya are the same it is known as Piśāca and if it
(Vyaya) is more than Āya it is known as Rākṣasa. The variety of
Vyaya designated as Cintātmaka is to be discarded among eight
types of āya.
44. The eight types of Vyaya are Śānta, Paura, Pradyota, Śriyānanda,
Manohara, Śrīvatsa, Vibhava and Chintātmaka.
45. Śānta in Dhvaja is always beneficial in a house. There will be
enjoy- ment prayer oblation, dance, song and instrumental music
if the same com- bination happens to be in a temple.
Thus ends the Vyaya.
46. In the source connected to Vyaya, an addition is to be done
with the letters of the name of the house. They are to be divided
by three, and known as Aṁśa. The remainder is Indra, Yama and
Nṛpa.
47. Indra and Dhvaja are auspicious for a palace, idol and phallus. Rāja
is always good for a city and a royal palace.
48. Yama brings in death for a house but is auspicious for Mother
(Tantra) Gaṇeśa, and others selling wine and meat, Bhairava and
other cruel Devas.
Thus ends the Aṁśaka.
49. From the star of the owner, count the number of the presiding
star of the house, then divide it by nine, the remainder is called
Tārā.
50. Śāntā, Manoharā, Krūrā, Vijayā, Kalahāvahā, Padminī, Rākṣasī, Vīrā,
Ānandā - these are the nine varieties .
51. The third one causes danger while fifth one reduces strength,
the seventh one causes loss of wealth, so these three stars should
be discarded.
Thus ends Tārā .
