Mind as Charioteer; Kṣetrajña, Tapas, and Dhyāna-Yoga
Adhyātma-Upadeśa
पार्थिवश्च सदा गन्धो गन्धश्न बहुधा स्मृत: । तस्य गन्धस्य वक्ष्यामि विस्तरेण बहून् गुणान्
pārthivaś ca sadā gandho gandhaś ca bahudhā smṛtaḥ | tasya gandhasya vakṣyāmi vistareṇa bahūn guṇān |
पार्थिवश्च सदा गन्धो गन्धश्च बहुधा स्मृतः। तस्य गन्धस्य वक्ष्यामि विस्तरेण बहून् गुणान्॥
वायुदेव उवाच
The verse states a classical doctrine of the elements: earth is characterized by smell (gandha), and smell itself has many varieties; the speaker promises a systematic account of its properties.
Vāyu-deva continues a didactic explanation about the natural elements and their defining qualities, turning specifically to earth and introducing an extended discussion of fragrance/smell.
