Tīrtha-vaṃśa Upadeśa: Instruction on the Fruits of Sacred Waters
अवषुष्ट च यद् भुक्तमव्रतेन च भारत । परामृष्टं शुना चैव तं भागं रक्षसां विदु:
avaṣuṣṭaṃ ca yad bhuktam avratena ca bhārata | parāmṛṣṭaṃ śunā caiva taṃ bhāgaṃ rakṣasāṃ viduḥ ||
بھیشم نے کہا—اے بھارت! وہ اناج جس کے بارے میں لوگوں میں اعلان کر دیا گیا ہو، جسے بے نذر و برت (بے طہارت) آدمی کھا چکا ہو، یا جسے کتے نے چھو دیا ہو—وہ بھی راکشسوں کا حصہ سمجھا جاتا ہے۔
भीष्म उवाच
Food intended for righteous use must be protected by discipline (vrata/ācāra) and purity; once it is improperly claimed, eaten by an undisciplined person, or contaminated (e.g., by a dog), it becomes unfit for dharmic consumption and is figuratively assigned to rākṣasas.
In Bhishma’s instruction to Yudhishthira on right conduct, he lists conditions under which food becomes ritually tainted—publicly called out/claimed, eaten by an avratin, or touched by a dog—and states that such a portion is regarded as belonging to rākṣasas, i.e., outside the sphere of proper human religious eating.
