Bhagavad Gita 18.40
न तदस्ति पृथिव्यां वा दिवि देवेषु वा पुनः । सत्त्वं प्रकृतिजैर्मुक्तं यदेभिः स्यात्त्रिभिर्गुणैः ॥
na tad asti pṛthivyāṃ vā divi deveṣu vā punaḥ / sattvaṃ prakṛti-jair muktaṃ yad ebhiḥ syāt tribhir guṇaiḥ
Translation
There is nothing on earth, nor in heaven among the gods, that is free from these three gunas born of prakriti.
Reflection
Where in your life have you been looking for a guna-free environment that does not exist?
Read this verse in its chapter: Chapter Eighteen
Universality statement. Krishna closes the diagnostic sweep with a sobering claim. Look anywhere, prithivi or divi, this earth or the heavens, even the realms of the devas, and nothing manifest is free of the three-guna economy. This is not pessimism. It is map-making. The seeker who imagines some pristine corner of the cosmos that is naturally beyond sattva, rajas, and tamas will spend a lifetime searching for an exit that does not exist within prakriti. The exit is elsewhere, in the next sequence of verses Krishna will introduce, the route through sva-karma toward atma and Ishvara. First the trap is named completely. Then the door.
