Mind as Charioteer; Kṣetrajña, Tapas, and Dhyāna-Yoga
Adhyātma-Upadeśa
शब्दस्पर्शीं च विज्ञेयौ द्विगुणो वायुरुच्यते
śabdasparśīṃ ca vijñeyau dviguṇo vāyur ucyate
风神伐由说道:“当知其本有之德为声与触;因此风被称为‘二分’——具足这两种感官属性。”
वायुदेव उवाच
The verse teaches an elemental doctrine: the air principle (vāyu) is characterized by two perceptible qualities—sound and touch—so it is termed ‘twofold’ (dviguṇa). This frames knowledge of the world through discernible properties rather than mere names.
Vāyu-deva is delivering a didactic explanation about the nature of the elements and their defining sensory qualities, classifying vāyu by the properties it carries (sound and touch).
