Mind as Charioteer; Kṣetrajña, Tapas, and Dhyāna-Yoga
Adhyātma-Upadeśa
यन्नैव गन्धिनो रस्यं न रूपस्पर्शशब्दवत् । मन्यन्ते मुनयो बुद्धया तत् प्रधान प्रचक्षते
yan naiva gandhino rasyaṁ na rūpasparśaśabdavat | manyante munayo buddhyā tat pradhānaṁ pracakṣate ||
ഗന്ധവും രസവും ഇല്ലാത്തതും, രൂപം-സ്പർശം-ശബ്ദം എന്നിവയാൽ യുക്തമല്ലാത്തതും—മുനികൾ വിവേകബുദ്ധിയാൽ ധ്യാനിക്കുന്നതും—അതിനെ തന്നെയാണ് അവർ ‘പ്രധാനം’ എന്നു വിളിക്കുന്നത്।
वायुदेव उवाच
The verse defines Pradhāna as the unmanifest primordial principle that is beyond the five sensory qualities (smell, taste, form, touch, sound) and is known not by the senses but by contemplative intellect; it points toward discernment and detachment from sense-based knowing.
Vāyu-deva is instructing by giving a philosophical definition: he contrasts sensory attributes with what sages grasp through buddhi, identifying that subtle, non-sensory basis as Pradhāna.
