दक्षिणा-दिक्, पितृपक्ष-प्रतिष्ठा, तथा कर्मगतिः — Suparṇa’s Cosmographic Instruction
एतस्मात् कारणाद् ब्रह्मन् पूर्वेत्येषा दिगुच्यते । यस्मात् पूर्वतरे काले पूर्वमेवावृता सुरै:
etasmāt kāraṇād brahman pūrvety eṣā dig ucyate | yasmāt pūrvatara-kāle pūrvam evāvṛtā suraiḥ ||
“因此,婆罗门啊,此方被称为‘东方’;因为在最古之古的时代,正是诸天最先环护并占有它,奉之为首要之方。”
युपर्ण उवाच
The verse offers an etymological-cosmological rationale: the East is termed ‘pūrvā’ because it is regarded as the ‘first/foremost’ direction, associated with primordial divine precedence. It reflects how sacred language links naming to perceived cosmic order and divine authority.
Yuparṇa addresses a Brahmin and explains why the eastern quarter is called ‘pūrvā’. He grounds the name in an ancient account that the gods first encompassed or claimed that direction, establishing its primacy.
