Meaning
The ṭīkā fills in the coded instructions. On the square he draws three lines running from west to east. The kūrca is a bunch of kuśa grass; with it he sprinkles water on the lines while saying the mantra hūṁ (kūrca is also the code name of that seed). "He should fetch fire with fire" (vahninā vahnim āharet): the commentary reads the first "fire" as the fire-seed, raṁ, so that the fire is brought while saying raṁ.

Commentary
Hariharānanda Bhāratī’s Sanskrit commentary, translated
"Tisraḥ" and the rest. In that maṇḍala, on the sthaṇḍila made a cubit in measure, three lines are to be drawn, with their tips to the east. Then, sprinkling those lines with the kūrca (a bunch of kuśa grass) with the mantra hūṁ, that is, wetting them with water, he should fetch (āharet, ānayet) fire with fire, with the mantra raṁ.
