न तदस्ति पृथिव्यां वा दिवि देवेषु वा पुनः । सत्त्वं प्रकृतिजैर्मुक्तं यदेभिः स्यात्त्रिभिर्गुणैः ॥ ४० ॥

Translation
There is not an entity, either on the earth or again in heaven among the Shining Ones, that is liberated from these three qualities, born of Matter.

Explanation
Krishna closes the guna discussion running since chapters 14 and 17 with a totalizing claim: nothing in the cosmos, not even the gods in heaven, stands outside sattva, rajas, and tamas. That universality is the load-bearing premise for what immediately follows — since no one is guna-free, every person’s nature carries some particular mixture, and the fourfold division of duty about to be laid out in verses 41-44 is presented as a description of where that mixture lands each person rather than an arbitrary social rule.
