Bhagavad Gita 14.23

नथवदासिनो गुणैर्यो न विचाल्यते |
गुणा वर्तन इत्येवं योऽवत्तिष्ठति नेङ्गते

Translation

Nor do we long for them in their absence. They remain neutral to the nature of the qualities and are not disturbed by them. Knowing that only the Gunas are active, they remain situated in the Self without getting distracted.
