Srimad-Bhagavatam: Canto 12 - Chapter 1 - Verse 11
Sanskrit:
अव्याकृतगुणक्षोभान्महतत्रिस्त्रवृतोऽहम: ।भूतसूक्ष्मेन्द्रियार्थानां सम्भव: सर्ग उच्यते ॥ ११ ॥
ITRANS:
avyākṛta-guṇa-kṣobhānmahatas tri-vṛto ’hamaḥbhūta-sūkṣmendriyārthānāṁsambhavaḥ sarga ucyate
Translation:
From the agitation of the original modes within the unmanifest material nature, the mahat-tattva arises. From the mahat-tattva comes the element false ego, which divides into three aspects. This threefold false ego further manifests as the subtle forms of perception, as the senses and as the gross sense objects. The generation of all these is called creation.
