c7.376

9.1 Two holes are made (at the ends of) a bamboo rod at a distance equal to the height of the sacrificer with uplifted hands, and a third hole is made at the middle. Having placed the bamboo rod along the east-west line, poles are fixed in the holes from the western extremity; two poles from the western side are then taken off, and a circle is drawn (about the pole in the eastern extremity) with the other end (from the west) towards south-east. The pole is then removed from (the hole in) the eastern extremity and fixed at the western extremity, and a circle is drawn (about the pole in the western extremity) with the other end (from the east) towards south-west. The bamboo rod is taken off and one end of it is fixed to the middle (of the east-west line) with a pole; it is then placed towards the south so as to pass over the point of intersections of the two circles and a pole is fixed in the hole at the other extremity. The bamboo rod is fixed to this (last) pole by its middle hole and laid (east-west) touching the outer edges of the two circles; two poles are fixed through the two extreme holes. This is a square of (side equal to) one *puruṣa*.
