Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 4

Sanskrit:

तयोरेकतरो ह्यर्थः प्रकृतिः सोभयात्मिका ।ज्ञानं त्वन्यतमो भावः पुरुषः सोऽभिधीयते ॥ ४ ॥

ITRANS:

tayor ekataro hy arthaḥprakṛtiḥ sobhayātmikājñānaṁ tv anyatamo bhāvaḥpuruṣaḥ so ’bhidhīyate

Translation:

Of these two categories of manifestation, one is material nature, which embodies both the subtle causes and manifest products of matter. The other is the conscious living entity, designated as the enjoyer.

Purport:

According to Śrīla Jīva Gosvāmī, prakṛti here refers to the subtle pradhāna, which later becomes manifest as mahat-tattva.
