Rudra-Śiva: Names, Two Natures, and the Logic of Epithets (रुद्रनाम-बहुरूपत्व-प्रकरणम्)
स शूद्र: संशिततपा: सत्यवादी जितेन्द्रिय: । शुश्रूषुरतिथिं प्राप्त तप: संचिनुते महत्
sa śūdraḥ saṃśitatapāḥ satyavādī jitendriyaḥ | śuśrūṣur atithiṃ prāptaṃ tapaḥ saṃcinute mahat ||
स शूद्रः संशिततपाः सत्यवादी जितेन्द्रियः। शुश्रूषुरतिथिं प्राप्तं तपः संचिनुते महत्॥ तस्य सेवारूपो धर्म एव कठोरं तप उच्यते।
श्रीमहेश्वर उवाच
Ethical excellence is measured by conduct: truthfulness, self-mastery, and hospitality. Serving an unexpected guest is presented as a form of tapas, generating great spiritual merit.
Mahādeva is instructing about dharma, highlighting that a Śūdra who practices truth, restraint, and devoted service to an arriving guest attains great tapas through service itself.
