4.2.30

brahma ca brāhmaṇāṃś caiva yad yūyaṃ parinindatha /
setuṃ vidhāraṇaṃ puṃsām ataḥ pāṣaṇḍam āśritāḥ //

30. Since you cast reproaches on the Vedas and Brāhmins, who are the defence of (or a dam to protect) men (following the duties of the *Varṇas* and *Āśramas*), you shall embrace the creed of the Pākhaṇḍas (the unbelievers).
