तथैकमात्मप्रकृती नाम्रा भिन्ने न सत्तया ॥ ३१ ॥

yathaikaḥ spandapavanau nāmnā bhinnau na sattayā ,
tathaikamātmaprakṛtī nāmrā bhinne na sattayā 31

31. yathā ekaḥ spandapavanau nāmnā bhinnau na sattayā
tathā ekam ātmaprakṛtī nāmnā bhinne na sattayā

31. yathā ekaḥ spandapavanau nāmnā bhinnau,
na sattayā; tathā ekam ātmaprakṛtī nāmnā bhinne,
na sattayā.

31. Just as pulsation (spanda) and wind (pavana), though referred to by two names, are fundamentally one in their true nature, not different in essence; similarly, the self (ātman) and nature (prakṛti), though called by two names, are fundamentally one in their true nature, not different in essence.
