Kashyapa — Saptarishi

Sage Kashyapa holds a uniquely foundational position among the Saptarishis as the progenitor of much of existing life, earning him the epithet 'Prajapati' for his role in populating the universe through his numerous consorts, the thirteen daughters of Daksha Prajapati. Born as the son of Marichi, one of the mind-born sons of Brahma, Kashyapa's marriages to Aditi and Diti produced two opposing yet related lineages: the Devas (gods) through Aditi and the Daityas (demons) through Diti, illustrating the Vedic understanding that divine and demonic forces spring from a common cosmic source, differentiated by their orientation toward dharma or adharma rather than by fundamental nature. Through his union with Danu, he fathered the Danavas, and through other wives, he is credited as the progenitor of nagas (serpents), birds including Garuda through Vinata, and various other beings, making him literally the father of the manifest world's diverse life forms in Puranic cosmology. His hermitage is traditionally associated with the Kashmir valley, with legend holding that he drained a vast lake called Satisar to create habitable land, after which the region was named Kashmir in his honor, reflecting his role as a civilizing and land-shaping figure in addition to his cosmogonic significance. Kashyapa is also credited with composing several hymns in the Rig Veda and is remembered in the Puranas for his role in counseling his warring children toward reconciliation, embodying the wisdom of a father figure who must maintain equanimity while presiding over cosmic conflicts between his own progeny. His pervasive presence across nearly all major Puranic genealogies makes him arguably the most universally significant ancestral figure in Hindu mythology.

Kashyapa fathered the Devas, Danavas, Nagas, and Garuda through his various consorts, is credited with founding the Kashmir valley by draining Satisar lake, composed hymns in the Rig Veda, and serves as the foundational patriarchal figure connecting nearly all beings in Puranic genealogy.
