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 ||
Por ello, ahora expondré, en el debido orden, cómo el principio vital (sattva) y el Conocedor del Campo (kṣetrajña) llegan a unirse y cómo se separan. Escuchad con suma atención esta enseñanza, oh los mejores entre los virtuosos, oh los más excelsos grandes rishis, pues atañe al entendimiento que guía la recta conducta y la libertad interior.
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.
