The Brahmana is the foremost of gods. It is not true that they that belong to that order do not celebrate the sacrifices of the other orders. The fire called Vitana, though procured from Vaishyas and inspired with mantras, is stili inferior. The Brahmana can celebrate the sacrifices of the three other castes.
स्वं दैवतं ब्राह्मणः स्वेन नित्यं परान्वर्णानयजन्नैवमासीत्। अधरो वितान: संसृष्टो वैश्यो ब्राह्मणस्त्रिषु वर्णेषु यज्ञसृष्टः॥
