कामिक आगम: पूर्व भाग (अष्टाविंशति मूल शैव आगमों का प्रथम एवं सर्वोच्च आगम महाकोश)

Having divided the side of the square into 5 equal parts, the Guru should mark a point in the middle of the
east side,having left out one part below the east line. He should mark two points above and below of the
east-west lines , at a distance two third of these two lines and having increased by two and a half angulas
on either side. Holding the diameter to be one fourth of the line, he should draw two circles at the north-west
and south-west and join the three points in the front and in the sides. A fire-pit in the form of vulva is
designed in this way. The basic square should be divided into nine equal parts and one part should be
left out in the front and at the bottom. Holding the diameter to be 7 parts, he should draw a half circle. The
fir-pit in the form of half-moon is formed in this way.

Then, in the north side, a line should be drawn in a desired direction(in the east side or the west side).
In the area increased by three parts, three intersecting circles should be drawn. By doing so, the
fire-pit pertaining to the south-west direction, triangular fire-pit could be formed. By removing eight
parts from the line which indicates the neck part of the fire-pit and by drawing a circle, circular fire-pit
could be formed. In the area increased by six parts, four intersecting circles should be drawn and with
the lines thus obtained, hexagonal fire-pit could be formed.
