Bhṛgu–Bharadvāja-saṃvāda: Vānaprastha-parivrājaka-ācāra, Abhaya-dharma, and Lokānāṃ Vibhāga (Śānti-parva 185)
एवं बहुविधाकार: शब्द आकाशसम्भव: । आकाशगजं शब्दमाहुरेभिवायुगुणैः सह,इस प्रकार आकाशजनित शब्दके अनेक भेद हैं। वायुसम्बन्धी गुणोंके साथ ही आकाशजनित शब्द होता है; ऐसा विद्वान पुरुष कहते हैं
evaṁ bahuvidhākāraḥ śabda ākāśasambhavaḥ | ākāśaguṇaṁ śabdam āhur ebhir vāyuguṇaiḥ saha ||
婆罗陀婆阇说道：“由虚空（ākāśa）而生之声，呈现多种形态。贤者宣说：声乃虚空之特质，而其被领受，须与风（vāyu）所系诸德相伴而知。”

Educational Q&A
The verse presents a classical element-and-quality doctrine: sound (śabda) is said to originate from ākāśa and is regarded as ākāśa’s defining quality, while its manifestation and apprehension are discussed alongside the qualities associated with vāyu.
In the didactic setting of Śānti Parva, Bharadvāja is explaining a philosophical account of how sensory qualities relate to the elements—here focusing on sound, its origin in space (ākāśa), and its relation to air (vāyu).
