identified with death (X. 165. 4, 'to Yama be reverence, to death'; I. 38.5; ib. 116. 2)[4]. There is always a close connection between Varuna and Yama, and perhaps it is owing to this that parallel to 'Varuna's fetters' is found also 'Yama's fetter,' i.e., death (x. 97. 16).
As Yama was the first to die, so was he the first to teach man the road to immortality, which lies through sacrifice, whereby man attains to heaven and to immortality. Hence the poet says, 'we revere the immortality born of Yama' (i. 83.5). This, too, is the meaning of the mystic verse which speaks of the sun as the heavenly courser 'given by Yama,' for, in giving the way to immortality, Yama gives also the sun-abode to them that become immortal. In the same hymn the sun is identified with Yama as he is with Trita (i. 163. 3). This particular identification is due, however, rather to the developed pantheistic idea which obtains in the later hymns. A parallel is found in the next hymn: "They speak of Indra, Mitra, Varuna, Agni ... that which is one, the priests speak of in many ways, and call him Agni, Yama, Fire" (or Wind, i. 164.46).
Despite the fact that one Vedic poet speaks of Yama's name as 'easy to understand' (x. 12. 6), no little ingenuity has been spent on it, as well as on the primitive conception underlying his personality. Etymologically, his name means Twin, and this is probably the real meaning, for his twin sister Yami is also a Vedic personage. The later age, regarding Yama as a restrainer and punisher of the wicked, derived the name from yam the restrainer or punisher, but such an idea is quite out of place in the province of Vedic thought. The Iranian Yima also has a sister of like name, although she does not appear till late in the literature.
That Yama's father is the sun, Vivasvant (Savitar, 'the artificer,' Tvashtar, x. 10.4-5),[5] is clearly enough stated in the Rik; and that he was the first mortal, in the Atharvan. Men come from Yama, and Yama comes from the sun as 'creator,' just as men elsewhere come from Adam and Adam comes from the Creator. But instead of an Hebraic Adam and Eve there are in India a Yama and Yam(=i], brother and sister (wife), who, in the one hymn in which the latter is introduced (loc. cit.), indulge in a moral conversation on
