Place the bamboo-rod on the east-to-west line and fix poles in the holes (beginning) from the western extremity of the sacrificial place. Then freeing the two poles (\*C\*, \*B\*) on the west, describe a circle (by rotating the bamboo) south-east-wise by the hole at the (opposite) end. Then unloosen-ning the eastern hole and fixing the hole in the west (in its original position), describe another circle south-westwise by the hole at the opposite end. Now release the bamboo (completely); fix again an extreme hole at the middle pole (\*C\*) ; place it towards the south over the point of intersection of the two circles and fix a pole at the point (\*F\*) reached by the outermost hole. Then fix at this pole the middle hole of the bamboo and having laid it along the extreme outer edges of the two circles,¹ fix two poles (\*E, D\*) at the two (outermost) holes. It (the figure thus described, \*ABDE\*) is a square (having a side) of one \*puruṣa\*.'' ² (Fig. 21.) - [Previous: c10.22](https://indike.org/pramana/ins.science.datta-1932.c10.22) - [Next: c10.24](https://indike.org/pramana/ins.science.datta-1932.c10.24) - [Up: c10](https://indike.org/pramana/ins.science.datta-1932.c10) --- Source: [https://indike.org/pramana/ins.science.datta-1932.c10.23](https://indike.org/pramana/ins.science.datta-1932.c10.23) · Pramāṇa
