8.21. [The scriptures] speak of This as Unmanifest and Changeless and declare This is to be the highest Goal. Having attained which people do not return, this is My highest abode.
Shri Purohit Swami
8.21 The wise say that the Unmanifest and Indestructible is the highest goal of all; when once That is reached, there is no return. That is My Blessed Home.

Sri Ramanuja
8.20 - 8.21 Superior, as an object of human end, to this unmanifest (Avyakta), which is inanimate Prakrti, there is another state of being, of a kind different from this, but also called Avyakta. It has only knowledge-form and is also unmanifest. It is the self, Atman. It is unmanifest because It cannot be apprehended by any means of knowledge (Pramanas). The meaning is that Its nature is unie and that It can be known only to Itself. That is, It can be understood only vaguely in the ordinary ways of knowing. It is eternal, namely, ever-enduring, because It is not subject to origination and annihilation. In texts like ‘For those who meditate on the imperishable, undefinable, the unmanifest’ (12.3) and ‘The imperishable is called the unchanging’ (15.16) - that being the self. It has been called the unmanifest (Avyakta) and imperishable (Aksara); when all material elements like ether, etc., with their causes and effects are annihilated, the self is not annihilated in spite of It being found alone with all the elements. [The elements are what constitute the bodies of beings.]
The knowers of the Vedas declare It as the highest end. The meaning is that the imperishable entity which has been denoted by the term ‘highest goal’ in the passage, ‘Whosoever abandons the body and departs (in the manner described) reaches the highest state (Dhama)’ (8.13), is the self (Atman) abiding in Its essential nature free from the contact with the Prakrti. This self, which abides thus in Its essential nature, by attaining which It does not return, - this is My ‘highest abode,’ i.e., is the highest object of My control. The inanimate Prakrti is one object of My control. The animate Prakrti associated with this inanimate Prakrti is the second object of My control. The pristine nature of the freed self, free from contact with inanimate matter, is the highest object of My rule. Such is the meaning. This state is also one of non-return to Samsara. Or the term ‘dhama’ may signify ’luminosity’. And luminosity connotes knowledge. The essential nature of the freed self is boundless knowledge, or supreme light, which stands in contrast to the shrunken knowledge of the self, when involved in Prakrti. [The description given above is that of Kaivalya, the state of self-luminous existence as the pure self].
Sri Krsna now teaches that the object of attainment for the Jnanin, is totally different from this:

8.21 He Himself who has been uktah, meantioned; as avyaktah, Unmanifest; the aksarah, Immutable; ahuh, they call; tam, Him-that very unmanifest Reality which is termed as the Immutable; the paramam, supreme; gatim, Goal. Tat, That; is the paramam, supreme; dhama, abode, i.e. the supreme State; mama, of Mine, of Visnu; yam prapya, reaching which Reality; na nivartante, they do not return to the worldly state. The means for gaining That is being stated:

8.21 He who has been mentioned as the Unmanifested, the Immutable, they call Him the supreme Goal. That is the supreme abode of Mine, reaching which they do not return.
8.21 What is called the Unmanifested and the Imperishable, That they say is the highest goal. They who reach It do not return (to this Samsara). That is My highest abode (place or state).

Commentaries
Swami Sivananda
8.21 अव्यक्तः unmanifested? अक्षरः imperishable? इति thus? उक्तः called? तम् That? आहुः (they) say? परमाम् the highest? गतिम् goal (path)? यम् which? प्राप्य having reached? न not? निवर्तन्ते return? तत् that? धाम abode (place or state)? परमम् highest? मम My.Commentary Para Brahman is called the Unmanifested because It cannot be perceived by the senses. It is called the Imperishable also. It is allpervading? allpermeating and interpenetrating. Para Brahman is the highest Goal. There is nothing higher than It. This is the true nondual state free from all sorts of limiting adjuncts. The attainment of Brahmaloka (the region of the Creator) etc.? is inferior to this. Only by realising the Self is one liberated from Samsara. (Cf.XII.3?XV.6)
