Bhagavad Gita 3.24

And if I were to refrain from action, the human race would be ruined; I would lead the world to chaos, and destruction would follow.

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

utsīdeyurime lokā na kuryāṃ karma cedaham|
saṅkarasya ca kartā syāmupahanyāmimāḥ prajāḥ||
