Puṣkara-Śapatha Itihāsa (Agastya–Indra Dispute at the Tīrthas) | पुष्कर-शपथ-आख्यानम्
उपाध्यायमध: कृत्वा ऋचो<ध्येतु अजूंषि च । जुहोतु च स कक्षाग्नौ बिसस्तैन्यं करोति यः:,जो मृणालकी चोरी करता हो, उसे उपाध्याय (अध्यापक या गुरु) को नीचे बैठाकर उनसे ऋग्वेद और यजुर्वेदका अध्ययन करने और घास-फ़ूसकी आगमें आहुति डालनेका पाप लगे
upādhyāyam adhaḥ kṛtvā ṛco 'dhyetuṃ yajūṃṣi ca | juhotu ca sa kakṣāgnau bisastainyaṃ karoti yaḥ ||
Bharadvāja said: “He who commits the theft of bisas (lotus-stalk fibres) incurs the same sin as one who, after making his teacher sit in a lower place, studies the Ṛgveda and the Yajurveda in a disrespectful manner and offers oblations into a mere grass-fire. The teaching is that even seemingly minor theft is a serious breach of dharma, and that sacred learning and ritual, when performed with contempt for the teacher and proper rite, become acts of wrongdoing rather than merit.”
भरद्वाज उवाच
The verse equates the theft of something seemingly small (lotus-stalk fibres) with grave religious misconduct: disrespecting one’s teacher while undertaking Vedic study and performing a degraded form of ritual. It teaches that dharma depends on intention, reverence, and right conduct—not merely on the external act.
Bharadvāja is enumerating and grading moral faults. He states that a person who steals bisas bears a sin comparable to someone who humiliates the upādhyāya, studies the Vedas in that disrespectful posture, and offers oblations into an improper ‘grass-fire,’ thereby turning sacred acts into wrongdoing.
