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

Ch. II – Āyādhikāraḥ 79 79-80. One should draw oneés own Varga and other Vargas serially. In one Varga, the sum of the Varga divided by eight remains static. On the half part of that, Vimśopā is to be placed at first. It should be considered for their own sake, house, village, in gain and loss. Thus ends Vimśopā. 81-82. According to Maya it is said to bring or (consider) Vāra and Tithi, separately. The height or length(?) is to be multiplied by seven and then take away thirty; the remainder is the Vāra and Tithis at the time of sun rise in both the Pakṣas. Bhauma (Tuesday), Arka days (Sunday) and Rikta, Yama, Utpāta, Mṛti Yogas are to be discarded. 83. Āya and other plans give happiness in all respects if they are made of seventeenth parts. Without a learned person this plan cannot be applied in a house within a short time. 84. So a wise person will plan his house by three, five, seven, nine parts; it is said by Śrī Viśvakarmā that faults should be less and good qualities should be more. 85. There will be amity among Āya, Ṛkṣa, Vyaya, Tārā, Aṁśa, moon, zodiac signs and planets. Life span will be determined by three, five, nine and results will accordingly follow. Thus ends the Second Chapter titled Command of Āya, in the Vāstumaṇḍana, the Science of Architecture, written by Sūtradhāra Maṇḍana.
