Mind as Charioteer; Kṣetrajña, Tapas, and Dhyāna-Yoga
Adhyātma-Upadeśa
अतः: पर प्रवक्ष्यामि सच्त्वक्षेत्रज्ञयोर्यथा । संयोगो विप्रयोगश्न तन्निबोधत सत्तमा:
ataḥ paraṁ pravakṣyāmi sattva-kṣetrajñayor yathā | saṁyogo viprayogaś ca tan nibodhata sattamāḥ śreṣṭha-maharṣayaḥ ||
ゆえに今、生命の原理(サットヴァ sattva)と「場を知る者」(クシェートラジュニャ kṣetrajña)がいかに結合し、いかに離別するかを、順を追って説き明かそう。徳ある者のうち最勝の者よ、偉大なる仙人たちの中でも第一の者よ—正しい行いと内なる解放を導く理解に関わるゆえ、心して聴け。
वायुदेव उवाच
Vāyudeva introduces an explanation of how the conscious knower (kṣetrajña) becomes associated with the principle of embodied experience (sattva) and how that association ceases—an inquiry meant to support discernment, ethical steadiness, and release from confusion about self and experience.
Vāyudeva addresses an audience of eminent seers, signaling a formal instruction: he is about to expound a doctrinal account of union and separation between sattva and kṣetrajña, asking them to listen with focused attention.
