c8.t28.65

**1.9-1.10.** Let A and G be the positions of *āhavanīya* and *gārhapatya* fire-altars. As explained by Mahīdhara, the distance AG is to be reduced by one-third. With a cord equal to this reduced length, that is AB, a square EFGD is drawn in the eastern part (Fig. 3), that is, from point A westward,: *pūrvārdhe āhavanīyamadhyāt paścimabhāge samacaturasramuktavidhinā kāryam* (Mahīdhara). At the southern *śroṇī* point D of this square (*dakṣiṇaśroṇyam*) the fire is to be placed. To determine the place of *utkara*, a similar figure UJKL is drawn in the western part, that is, from the *gārhapatya* point G towards east: *paścimārdhe gārhapatyasya madhyāt pūrvabhāge*. Then U, the northern *aṃsa* point of the square is the *utkara*.
