Thus, Manu and other teachers, not knowing who were real Brāhmaṇas, could not have imparted the teachings to Brāhmaṇas alone: because they could not be sure of it.—(3581)

Kamalaśīla

Then again, it is not only for yourselves that it is not right to indulge in arrogance due to your Brāhmaṇa-hood, which is open to doubt; as regards Manu and other teachers also,—as they could not know who were real Brāhmaṇas, the Teachings, if imparted to Brāhmaṇas alone, must have been imparted under a delusion.—This is pointed out in the following—[see verse 3581 above]

‘Avijñāta’—Those who could not bo sure of the Brāhmaṇa-hood of any one.

‘Tadaniścayāt’—Because they could not be sure of people being Brāhmaṇas.—(3581)
