Next in order was the _Kârusha_ race inhabiting the north.
The âgavataPurâ_Dhârshtas_ were also a spiritual race (Brâhmanas).
The descent towards Materiality commenced with Nriga. He is said to have been transformed into a lizard. His grandson was _Bhûtajyotî_, Bhûtas being different forms of matter. _Vasu_ is a God of Material wealth. _Pratîka_ means the reverse or opposite (_i.e._ the reverse of spirit.) _Ogha_ means a current. The current of materialism set in with the line of Nriga.
The next line, that of Narishyanta, shews further materiality. Midhvat is that which wets (the root _mih_ means to pass water). _Viti_ is production, enjoyments. Vitihotra is the name of a sacrificial fire. _Agnivesya_ is an incarnation of Agni or the Fire-God, but he is nick-named Kânina or son of an unmarried woman and also _Jâtukarna_ (the name of a Vedic Rishi). There seems to have been sexual procreation in this line. The incarnation of Agni further indicates that the present human form was complete, for Agni is the form-giving energy in Nature.
In the next line of _Dishta_ we have _Vatsapriti_ or affection for children, _Pransu_ or tall, _Pramati_ or full-grown intellect, _Khanitra_ or digger, _Châkshusha_ or the eyed, and _Khaninetra_ or the hollow-eyed. This line represents the race of the earliest diggers, very tall, with the hollow eye predominant in them as a characteristic feature; this race was very powerful and capable of direct communion with the Devas, and the gods acted as waiters in the Yajna of Marutta.
The line of Saryâti refers to Ânarta and a town named Kusasthalî, built in the midst of the Sea. Evidently the continent on which the race flourished is now under water. Ânarta is supposed to be Sourâshtra (modern Surat.) But the site of Kusasthalî cannot be ascertained. There were remnants of this race till the time of Krishna, for Balarâm married Revati, the daughter of Kakudmin (hump-backed). The line of Nabhaga is a short one and it merged itself into that of Angiras who was the father of Brihaspati or Jupiter. Ambarisha is the prominent figure of this period.
Then we come to the line of _Ikshvâku_. This is the best known line of the Solar races. It flourished during the last Tretayuga. _Ikshvâku_ is called the eldest son of Manu. Perhaps this has reference to the appearance of the Race in the previous Manvantaras.
