Adhyāya 42 — Mahābhūta–Indriya–Adhyātma-Vyavasthā
Brahmā’s Instruction on Elements and Faculties
यथाग्निरिन्धनैरिद्धों महाज्योति: प्रकाशते । तथेन्द्रियनिरोधेन महानात्मा प्रकाशते
yathāgnir indhanair iddho mahājyotiḥ prakāśate | tathendriya-nirodhena mahān ātmā prakāśate ||
Như lửa được thêm củi thì bùng cháy và rực sáng với hào quang lớn lao, cũng vậy, khi các căn được nhiếp phục, Đại Ngã (Đại Tự Ngã) liền hiển lộ—ánh sáng của Ngài được cảm nhận rõ rệt hơn.
वायुदेव उवाच
Sense-restraint (indriya-nirodha) is presented as the practical means by which the inner Self’s luminosity becomes evident. As fuel makes fire blaze visibly, disciplined control of the senses makes the Self’s presence and clarity more directly experienced.
Vāyudeva is instructing the listener through a vivid simile: fire’s radiance increases when properly fed, and likewise the ‘great Self’ becomes manifest when the senses are brought under control. The verse functions as a didactic moment emphasizing yogic discipline within the broader post-war ethical-spiritual instruction of the parva.
