But verily there exists, higher than this Unmanifested, another unmanifested Eternal, which is not destroyed when all beings are destroyed.
In simple words
Krishna reveals something beyond the cycle: "But beyond this visible and invisible nature — beyond everything that appears and disappears — there is another reality, eternal and indestructible, which is not destroyed even when everything else is."

8.20 परः higher? तस्मात् than that? तु but? भावः existence? अन्यः another? अव्यक्तः unmanifested? अव्यक्तात् than the unmanifested? सनातनः Eternal? यः who? सः that? सर्वेषु all? भूतेषु beings? नश्यत्सु when destroyed? न not? विनश्यति is destroyed.Commentary Another unmanifested in the ancient or eternal Para Brahman Who is distinct from the Unmanifested (Avyakta or Primordial Nature)? Who is of ite a different nature. It is superior to Hiranyagarbha (the Cosmic Creative Intelligence) and the Unmanifested Nature because It is their cause. It is not destroyed when all the beings from Brahma down to the ants or the blade of grass are destroyed. (Cf.XV.17)

This interpretation draws on a specific tradition and may not represent the view of any single school. For authoritative guidance within a specific tradition, seek a qualified teacher.
In a school classroom, there is a blackboard that many teachers use in a single day to explain different subjects. Each teacher erases the letters written by the previous teacher and teaches their own subject. The mathematics teacher draws figures of arithmetic or geometry, while the geography teacher draws maps showing rivers, mountains, and other geographical features. The chemistry teacher explains chemical reactions and formulas, and the history teacher imparts knowledge of ancestral lineages and traditions. Each teacher expresses their knowledge through different numbers, figures, and symbols. Although the subjects and figures of all teachers are different, the blackboard used by all of them is one and the same.
Similarly, this ever-changing world—which is the manifest form of the unmanifest—requires an unchanging substratum that does not perish even when all beings perish. When all students and teachers leave for their homes in the evening, the blackboard still remains in its place. This consciousness principle, which is itself beyond the grasp of the senses, mind, and intellect, and is therefore called unmanifest, is the substratum of this world. This is what Lord Sri Krishna indicates in His teaching. But beyond this unmanifest, there exists another eternal, imperishable reality.
Thus we see that here both the cause of manifest creation and the consciousness principle are called unmanifest. However, the difference between them is this: the consciousness principle never becomes manifest and is never the subject of proof, whereas the causal state of creation, which is called unmanifest, becomes manifest in subtle and gross forms at the beginning of each cosmic cycle.
The unmanifest (vasanas—latent tendencies) is the seed state of manifest creation, which Vedanta also calls avidya (ignorance). Ignorance is not itself a thing, but ignorance can only exist regarding something that exists. A person cannot be ignorant of his own tail, because a tail is non-existent. From this, the existence of a real, eternal truth becomes evident.
Just as the blackboard is the substratum for the knowledge taught in the classroom, so too this consciousness principle is the foundation of creation. Not knowing this truth is avidya, which manifests this ever-changing creation of name and form. Beyond this creation born of avidya—which undergoes repeated cycles of creation, sustenance, and dissolution—there exists a principle that is indicated here by the words "eternal, imperishable reality."
Is this unmanifest itself the supreme principle, or is there a superior reality beyond this eternal, imperishable principle worthy of being the goal of life?
