हृदि नारायणश्चास्ते अश्विनौ पूर्वपादयोः । वरुणश्चार्यमा चैव पश्चिमे तस्य सक्थिनी ॥ ३२ ॥ शिश्नः संवत्सरस्तस्य मित्रोऽपानं समाश्रितः ॥ ३३ ॥
The Áswins are its two fore feet; and Varuńa and Áryamat its two hinder legs. Samvatsara is its sexual organ; Mitra its organ of excretion. — H.H. Wilson (1840; public domain)
Grouped because they share a single source-passage and an identical evidential status: each is a NAMED position on the star-figure, but no Purāṇa assigns any of them a visible star, and the older recension's figure has only fourteen stars for far more than fourteen named positions. Dharma also appears independently in the Bhāgavata's tail-group (5.23.5), where it is a different position on a different version of the figure. Any star-by-star mapping of these is reconstruction, not text.
