ब्राह्मणा ब्रह्मतन्त्रस्थास्तपस्तेषां न नश्यति । ब्रह्म धारयतां नित्य॑ं व्रतानि नियमांस्तथा
brāhmaṇā brahmatantrasthās tapas teṣāṃ na naśyati | brahma dhārayatāṃ nityaṃ vratāni niyamāṃs tathā ||
婆罗堕阇说道：“凡婆罗门安住于梵之法度（梵行之纪律）者——依吠陀之戒命而行，恒以忆念与诵持摄持梵（Brahman），并坚守誓戒与制约——其苦行（tapas）之果永不失落。其tapas不灭，因其根植于正行，并以信诚奉持神圣法则。”

Educational Q&A
Austerity bears lasting fruit when it is grounded in Brahman/Vedic discipline—i.e., when one lives under scriptural guidance, maintains constant remembrance/holding of Brahman, and practices vows (vrata) and restraints (niyama). Such tapas is not wasted or destroyed.
In the didactic setting of the Śānti Parva, Bharadvāja states a principle about spiritual practice: brāhmaṇas who remain firmly established in Vedic-spiritual discipline and consistent observances retain the enduring merit of their austerities.
