Mind as Charioteer; Kṣetrajña, Tapas, and Dhyāna-Yoga
Adhyātma-Upadeśa
एवं धर्मस्य विज्ञेयं संसाधनमुपायत: । उपायज्ञो हि मेधावी सुखमत्यन्तमश्लुते
evaṃ dharmasya vijñeyaṃ saṃsādhanam upāyataḥ | upāyajño hi medhāvī sukham atyantam aśnute ||
ฉะนั้นพึงใคร่ครวญให้รู้ “วิธีการ” อันเป็นเครื่องยังธรรมให้สำเร็จ; เพราะบัณฑิตผู้รู้วิธี ย่อมบรรลุความสุขอย่างยิ่ง
वायुदेव उवाच
Dharma is not only an ideal but something to be realized through appropriate, well-understood means (upāya). The discerning person who knows how to apply the right method achieves lasting well-being.
Vāyudeva is speaking in an instructive mode, emphasizing that one must learn the practical instruments and strategies by which dharma is fulfilled; wisdom lies in knowing the proper means, which leads to supreme happiness.
