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

ब्रह्मस्थानस्य नैर्ऋत्यां शङ्कुस्थापनं प्रकल्पयेत् ।
अन्यत्र स्थापितं शङ्कुर्ग्रामाद्यं नाशयिष्यति ।। ३
brahmasth'anasya nairr'tya'm s'an'kustha'nam prakalpayet /
anyatra stha'pitam s'an'kur gr'a'ma'dyam na's'ayis"yati // 3
Let the priest perform the erection of gnomon exactly in the south-west of
the central grid (brahmastha'na). The gnomon erected in a place other than
the prescribed point will lead to decay and destruction of the villages, towns
and other constructions.
दण्डप्रमाणं विस्तारं षडङ्गुलं समुन्नतम् ।
शङ्क्वर्थं मण्डलं कुर्याद्देवानां च सनातनम् ।। ४
dan.d'aprama'n.a vista'ram s"d'an'gula samunnatam /
s'ankvartham man.d'alm kurya'd deva'na'm ca sana'tanam // 4
For the sake of erecting the gnomon, let the priest design a man.d'ala
according to the settled directions of the Agamas so as to appear pleasing
to the gods. The man.d'ala should be of one cubit(dan.d'a) in size, with the
proportionate height of six an'gulas.
The term an'gula cannot be translated as inch.
This term is to be retained as it is. In the system of
Agamas and S'ilpa S'a'stras one angula measures one
and three by eight inches.
