Meaning
The verse codes the mantra. "Havyavāha", the carrier of oblations, is fire, whose seed letter is ra; kṣa standing on it gives the conjunct kṣra. The six long vowels are ā, ī, ū, ai, au and the final visarga-vowel, and nāda and bindu add the nasal. The commentary assembles it: kṣrāṁ kṣrīṁ kṣrūṁ kṣraiṁ kṣrauṁ kṣraḥ. These six seeds are the mantra of Vāstu, used in his worship and his homa. What the Tantra prescribes here is its own teaching, given as the text presents it; taking up any practice is a matter for one's tradition and teacher.

Commentary
Hariharānanda Bhāratī’s Sanskrit commentary, translated
He tells the mantras of Vāstu and the rest in order, with "kṣakāraḥ" and the rest. Havyavāhasthaḥ: havyavāha, the carrier of oblations (fire), is the letter ra; standing on it, the letter kṣa, joined to the six long vowels and adorned with nāda and bindu, is to be made. So the six-syllabled Vāstu mantra was drawn out: kṣrāṁ kṣrīṁ kṣrūṁ kṣraiṁ kṣrauṁ kṣraḥ.
