Chapter 8, Verse 26
शुक्लकृष्णे गती ह्येते जगतः शाश्वते मते।
एकया यात्यनावृत्तिमन्ययाऽऽवर्तते पुनः।।8.26।।
According to the Vedas, there are two ways of passing from this world—one in light and one in darkness. When one passes in light, he does not come back; but when one passes in darkness, he returns.
