Mind as Charioteer; Kṣetrajña, Tapas, and Dhyāna-Yoga
Adhyātma-Upadeśa
बीजधर्म तथाव्यक्तं प्रसवात्मकमेव च । बीजधर्मा महानात्मा प्रसवश्चेति नः श्रुतम्,अव्यक्त प्रकृति कारणरूपा भी है और कार्यरूपा भी। इसी प्रकार महत्तत्त्वके भी कारण और कार्य दोनों ही स्वरूप सुने गये हैं
bījadharma tathāvyaktaṃ prasavātmakam eva ca | bījadharmā mahānātmā prasavaś ceti naḥ śrutam |
قال فايُو: «يُقال إنّ غير المتجلّي (Avyakta) ذو طبيعة البذرة، وهو مُنتِجٌ مُولِّدٌ يبعث الخلق. وكذلك سُمِع عن المبدأ العظيم (Mahat) أنّه يجمع بين كونه كبذرةٍ (أصلًا سببيًّا) وكونه “إنتاجًا” (أثرًا يُنْتِج بدوره).»
वायुदेव उवाच
The verse presents a causal chain in which the Unmanifest (Avyakta) and the Great Principle (Mahat) are each described as both cause (seed-like ground) and effect (a produced stage that itself produces further evolutes). It emphasizes layered causality: what is ‘born’ can still function as a ‘seed’ for what follows.
Vāyudeva is instructing the listener in a philosophical exposition (Sāṅkhya-like) about the origins of manifestation, explaining how Avyakta and Mahat are traditionally understood as simultaneously causal and productive principles within the unfolding of creation.
