Sāṅkhya Enumeration of Tattvas, Distinction of Puruṣa–Prakṛti, and the Mechanics of Birth and Death
प्रकृतिर्गुणसाम्यं वै प्रकृतेर्नात्मनो गुणा: । सत्त्वं रजस्तम इति स्थित्युत्पत्त्यन्तहेतव: ॥ १२ ॥
prakṛtir guṇa-sāmyaṁ vai prakṛter nātmano guṇāḥ sattvaṁ rajas tama iti sthity-utpatty-anta-hetavaḥ
प्रकृति मूलतः तीन गुणों के साम्य रूप में रहती है; ये गुण आत्मा के नहीं, केवल प्रकृति के हैं। सत्त्व, रज और तम—सृष्टि, स्थिति और प्रलय के कारण हैं।
In Bhagavad-gītā (3.27) it is stated:
This verse explains that sattva, rajas, and tamas belong to prakṛti (material nature) and function as the causes behind creation, maintenance, and dissolution; they do not belong to the ātmā.
To establish clear discrimination between the self and matter: the soul is conscious and transcendental, while the gunas are material forces that act within prakṛti and drive worldly change.
Identify moods and impulses as effects of sattva/rajas/tamas rather than as your true self, and cultivate devotion and clarity so choices are guided by spiritual identity instead of material conditioning.
