O, the Sages!, then I will explain in details the process of drawing the intersecting
lines, diagonal lines and such others and of identifying the acceptable and the
avoidable parts inside the selected plot. First, the expert(in va'stu) should draw a line
eastwards from the central grid (brahma stha'na) with the accompaniment
of bali-offering.
द्वितीयं स्यात् उदक्सूत्रं तस्मिन्नपि बलिं क्षिपेत्।
चतुरश्रायताश्रस्थ पर्यन्तं स्यात्तृतीयकम्।। २

The second line is to be drawn towards north from the same central grid.
Even for this line, the expert should offer the recommended bali. The
third line to be drawn is the boundary line (paryanta su'tra) coinciding
with the enclosing four sides of the square or rectangular mandala.
