Who is speaking and story frame
त्वमेक आद्य: पुरुषोऽद्वितीय-
स्तुर्य: स्वदृग् धेतुरहेतुरीश: ।
प्रतीयसेऽथापि यथाविकारं
स्वमायया सर्वगुणप्रसिद्ध्यै ॥ ३८ ॥
tvam eka ādyaḥ puruṣo ’dvitīyas
turyaḥ sva-dṛg dhetur ahetur īśaḥ
pratīyase ’thāpi yathā-vikāraṁ
sva-māyayā sarva-guṇa-prasiddhyai
You are the original person, one without a second, transcendental and self-manifesting. Uncaused, you are the cause of all, and You are the ultimate controller. You are nonetheless perceived in terms of the transformations of matter effected by Your illusory energy — transformations You sanction so that the various material qualities can fully manifest.
