Instruction on the Cessation of Craving
द्वाराणि यस्य सर्वाणि सुगुप्तानि मनीषिण: । उपस्थमुदरं बाहू वाक् चतुर्थी स वै द्विज:,जिस मनीषी पुरुषके उपस्थ, उदर, हाथ-पैर और वाणी--ये सभी द्वार पूर्णतः रक्षित हैं, वही वास्तवमें ब्राह्मण है
dvārāṇi yasya sarvāṇi sugoptāni manīṣiṇaḥ | upastham udaraṃ bāhū vāk caturthī sa vai dvijaḥ ||
Kapila said: The truly wise person is one whose gateways are all well-guarded—sexual impulse, the belly’s appetite, the arms (i.e., the power to act and seize), and speech as the fourth. Such a self-restrained one alone deserves to be called a “twice-born” (brāhmaṇa in the ethical sense), for his conduct is protected by discipline rather than driven by desire.

Brahminhood is defined by disciplined restraint: guarding desire (sex), appetite (food), the power of action (arms), and speech. Ethical identity is grounded in self-mastery rather than mere birth or ritual.
In the Śānti Parva’s instruction on dharma and liberation-oriented conduct, Kapila delivers a didactic statement redefining the ‘dvija’ as the person who protects key ‘gates’ of behavior through vigilance and wisdom.
