The former mantra is vaṁ, the seed of water; vāyu is yaṁ, the seed of air. On each strip of kuśa three piṇḍas are laid: the father's at the root, the grandfather's in the middle, the great-grandfather's at the tip; and so for each line.

Commentary
Hariharānanda Bhāratī’s Sanskrit commentary, translated
"Pūrvamantreṇa" and the rest. O Śivā, then, sprinkling the maṇḍalas with the mantra told before, in the form of the seed vaṁ, the skilled performer of the śrāddha should spread kuśa on those maṇḍalas. Then, sprinkling the darbha with vāyu, the seed yaṁ, in the order of the fathers' darbha, at the root, in the middle and at the top of the darbha, he should offer three piṇḍas each, in order, to the father and the rest, the mother and the rest, the maternal grandfather and the rest, and the maternal grandmother and the rest.
