Viśvāmitra-janma: Ṛcīka–Satyavatī–Gādhi and the Charu Exchange (विश्वामित्र-जन्म: ऋचीक–सत्यवती–गाधि वृत्तान्तः)

Bhishma dijo: “Sus hijos fueron hombres magnánimos—ascetas y conocedores de Brahman—que acrecentaron la estirpe de la tradición brahmánica y llegaron también a ser fundadores de clanes (gotras).”
भीष्म उवाच
The verse praises an ideal of dharmic continuity: spiritual discipline (tapas) and realization/learning (brahmavidyā) are presented as the true forces that strengthen a sacred lineage and establish enduring social-spiritual institutions like gotras.
Bhishma is describing the descendants (sons) of a previously mentioned figure, characterizing them as noble ascetics and knowers of Brahman who expanded the Brahmin tradition and became recognized founders of clan lineages (gotras).
