Verse 1: He was filled with passion (manyu, or kāma depending on the reading), from him sprang the Rājanya. The Rājanya is the warrior aristocracy that later becomes Kshatriya. Two hymns later (XV.10) Priesthood (Brahmanya) and Royalty (Kshatra) will both be derived from the Vrātya. The poet is making a remarkable structural claim: both the priestly and the royal varnas descend from this wanderer, who stands outside both. Falk reads this as evidence for the Männerbund origin of the warrior class itself — bands of armed initiates from whom the settled warrior aristocracy slowly crystallized. Heesterman reads it as a kingship-from-renunciation pattern: only the one who has stepped outside the system can ground its highest stations.
