Bhagavad Gita 8.26

शुक्लकृष्णे गती ह्येते जगतः शाश्वते मते।एकया यात्यनावृत्तिमन्ययाऽऽवर्तते पुनः ॥८.२६॥

śuklakṛṣṇe gatī hyete jagataḥ śāśvate mateekayā yātyanāvṛttimanyayā’’vartate punaḥ

The bright and dark paths of the world are thought to be eternal; one leads to no return, and the other leads to return.
