महाभारतः mahābhārataḥ - book-12, chapter-63, verse-10

लोके चेदं सर्वलोकस्य न स्याच्चातुर्वर्ण्यं वेदवादाश्च न स्युः ।
सर्वाश्चेज्याः सर्वलोकक्रियाश्च सद्यः सर्वे चाश्रमस्था न वै स्युः ॥१०॥

10. loke cedaṁ sarvalokasya na syā;ccāturvarṇyaṁ vedavādāśca na syuḥ ,
sarvāścejyāḥ sarvalokakriyāśca; sadyaḥ sarve cāśramasthā na vai syuḥ.

10. loke ca idaṃ sarvalokasya na syāt
cāturvarṇyaṃ vedavādāḥ ca na syuḥ
sarvāḥ ca ijyāḥ sarvalokakriyāḥ ca
sadyaḥ sarve ca āśramasthāḥ na vai syuḥ

10. ca cet idaṃ cāturvarṇyaṃ sarvalokasya
loke na syāt vedavādāḥ ca na syuḥ
sarvāḥ ijyāḥ ca sarvalokakriyāḥ ca
vai ca sarve āśramasthāḥ sadyaḥ na syuḥ

10. And if this system of the four social classes (cāturvarṇya) did not exist in the world for all people, then neither the Vedic injunctions, nor all forms of worship, nor all human activities would exist. Indeed, all those who abide in the stages of life (āśramas) would immediately cease to be.
