Bhagavad Gita 8.20 is Chapter 8, Verse 20, in Aksara Brahma Yoga (The Imperishable Brahman). Below are the Sanskrit text, a transliteration, a plain-English translation and an explanation.
paras tasmāt tu bhāvo 'nyo 'vyakto 'vyaktāt sanātanaḥ yaḥ sa sarveṣu bhūteṣu naśyatsu na vinaśyati
"But beyond this unmanifest, there is another unmanifest, eternal existence, which does not perish even when all beings perish."
What This Means:
Beyond the unmanifest that cycles (dissolving and emerging), there's ANOTHER unmanifest, the truly eternal (sanatana) that never perishes, even when everything else does.
Going Deeper:
There are two 'unmanifests': the cosmic seed from which manifestation emerges and returns, and the transcendent reality beyond even that. The first is still within time; the second is beyond time entirely.
How To Apply This:
There's a level of reality that remains unchanged regardless of what happens in the world or even in the cosmos. This is what you're seeking, not just a better state, but the changeless.
