Mind as Charioteer; Kṣetrajña, Tapas, and Dhyāna-Yoga
Adhyātma-Upadeśa
शब्द: स्पर्शस्तथा रूपं द्रवश्वाणां गुणा: स्मृता:
śabdaḥ sparśas tathā rūpaṁ dravaśvāṇāṁ guṇāḥ smṛtāḥ
वायुरुवाच—शब्दः स्पर्शस्तथा रूपं द्रवाणां गुणाः स्मृताः ॥
वायुदेव उवाच
The verse classifies sensory qualities (guṇas) associated with a category of matter—here, fluids—by listing sound, touch, and form. It reflects a traditional analytic framework used to explain how the world is experienced through the senses and how material categories are distinguished by their perceptible attributes.
Vāyu-deva is speaking in a didactic passage, presenting a systematic account of the qualities of substances/elements. The statement functions as part of a broader explanatory discourse on the constitution of the world and the properties by which different kinds of matter are known.
