When the third division (tryaṃśa) falls in the sign called Khaga, and the final portion is joined with planets, then—through the influence of Śauri (Saturn) and the combination known as dvīkṣā-yoga—Brahmins are born in the lineage (vāṃśa) called Sthalāmbuja.

It frames Jyotiṣa (a Vedāṅga) as a dharmic tool: celestial configurations are presented as part of the orderly karmic pattern through which births, tendencies, and social lineages manifest.
Indirectly: by emphasizing cosmic order and karma, it supports the Mokṣa-dharma message that one should not cling to birth-based identity but pursue liberation through disciplined dharma and devotion beyond mere lineage.
Jyotiṣa: the use of divisional measures like tryaṃśa, planetary conjunctions (grahānvita), and named yogas (dvīkṣā-yoga) to interpret outcomes such as birth in a particular lineage.
