Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 3
Sanskrit:
श्रीशुक उवाचशिव: शक्तियुत: शश्वत् त्रिलिङ्गो गुणसंवृत: ।वैकारिकस्तैजसश्च तामसश्चेत्यहं त्रिधा ॥ ३ ॥
ITRANS:
śrī-śuka uvācaśivaḥ śakti-yutaḥ śaśvattri-liṅgo guṇa-saṁvṛtaḥvaikārikas taijasaś catāmasaś cety ahaṁ tridhā
Translation:
Śrī Śukadeva said: Lord Śiva is always united with his personal energy, the material nature. Manifesting himself in three features in response to the entreaties of nature’s three modes, he thus embodies the threefold principle of material ego in goodness, passion and ignorance.
