Dvitīya-prakaraṇam (Niyama) · Verse 8
सिद्धान्तश्रवणं प्रोक्तं वेदान्तश्रवणं बुधैः । द्विजवत्क्षत्रियस्योक्तं सिद्धान्तश्रवणं बुधैः ॥
siddhāntaśravaṇaṃ proktaṃ vedāntaśravaṇaṃ budhaiḥ | dvijavatkṣatriyasyoktaṃ siddhāntaśravaṇaṃ budhaiḥ ||
The verse establishes a profound equivalence between siddhānta – traditionally understood as established principles or conclusions – and vedānta – the ultimate wisdom of the Upanishads. This declaration, “listening to siddhānta is declared by the wise as listening to vedānta,” immediately situates the yogic path within a broader intellectual and spiritual tradition. The “wise” (buddhi) are those who have recognized the essential unity underlying all phenomena, a concept central to Vedānta. The analogy extends beyond mere hearing; it suggests a receptive engagement with a system of thought that has been rigorously tested and validated. This parallels the Patañjali’s emphasis on the structured nature of samādhi and the importance of a foundational understanding, akin to a carefully constructed āsana before embarking on deeper meditation. The inclusion of the kshatriya and dvija – the warrior and twice-born classes – highlights the universality of this wisdom, suggesting that its attainment is open to all who cultivate the appropriate mental disposition.
