Bhagavad Gita · 3.24

उत्सीदेयुरिमे लोका न कुर्यां कर्म चेदहम्।सङ्करस्य च कर्ता स्यामुपहन्यामिमाः प्रजाः॥

utsīdeyur ime lokā na kuryāṁ karma ched aham saṅkarasya cha kartā syām upahanyām imāḥ prajāḥ

If I were to cease acting, these worlds would perish. I would be the cause of confusion and chaos, and I would destroy all these people.
