Following the path of the cakra as it pierced the seven coverings of the universe, going beyond that, Arjuna saw that supreme light which was beyond prakrti, beyond the eighth layer of prakrti (tamah param). Seeing that spiritual, most excellent (param) light spread everywhere (sam asnuvanam), he closed his eyes. This light is decribed in the Harivamsa at end of the narration. "That great shining entity composed of the light of Brahman is myself, o best of the bharatas. It is my eternal effulgence. It is my eternal superior prakrti, both manifest and unmanifest. The best knowers of yoga become liberated on entering it. It is the goal of those practicing sankhya, yoga and austerity. The whole universe worships that supreme Brahman. You should know that the intense effulgence is mine." He states that brahman is his effulgence, but also states that he is the effulgence. That is because the owner of the effulgence and the effulgence are considered non different. He also states that the Brahman is his prakrti. That spiritual brahma is his svarupa sakti beyond the touch of maya. It is manifest to spiritual eyes, but not manifest otherwise.

Then by following the path of the cakra, they crossed prakṛti, by piercing the seven layers of matter. Arjuna then saw the light of the Lord, parabrahman, famous in the Vedānta, by his eyes endowed with cit-śakti. Its supreme position is described with the word “infinite” because it was spread everywhere at all times (sam--aśnuvānam). Arjuna describes this in Hari-vaṁśa: tatas tejaḥ prajvalitam apaśyaṁ tat tad ambare / sarva-lokaṁ samāviśya sthitaṁ puruṣa-vigraham // In space, I saw the brilliant light entering all planets, which were situated with a human form. Hari-vaṁśa 103.24 After the incident Kṛṣṇa gives instructions: brahma-tejo-mayaṁ divyaṁ mahat yad dṛṣṭavān asi ahaṁ sa bharata-śreṣṭha mat-tejas tat sanātanam The divine expanse of Brahman effulgence you have seen is none other than myself, O best of the Bhāratas. It is my own eternal effulgence. Kṛṣṇa says that he is that light, since the effulgence and the cause of the effulgence are one. prakṛtiḥ sā mama parā vyaktāvyaktā sanātanī tāṁ praviśya bhavantīha muktā yoga-vid-uttamāḥ It comprises my eternal, spiritual energy, both manifest and unmanifest. The foremost yoga experts of this world enter within it and become liberated. This is his prakṛti since it arises from his svarūpa-śakti. It is superior (parā) because it is beyond māyā. It is the root of everything and is thus what is manifest and unmanifest. Therefore the yogīs enter it. sā sāṅkhyānāṁ gatiḥ pārtha yogināṁ ca tapasvinām tat paraṁ paramaṁ brahma sarvaṁ vibhajate jagat mamaiva tad ghanaṁ tejo jñātum arhasi bhārata It is the supreme goal of the followers of Sāṅkhya, O Pārtha, as well as that of the yogīs and ascetics. It is the Supreme Absolute Truth, manifesting the varieties of the entire created cosmos. You should understand this brahma-jyoti, O Bhārata, to be my concentrated personal effulgence. Hari-vaṁśa This is my effulgence. The word eva is added after mama to indicate that it is non-different from him, since he resides within it with eight arms.

The light was endless (ananta-param) because it spread everywhere at all times (samaśnuvānam). Seeing that light in front of him (prasamīkṣya), he felt extreme (pra) pain in his eyes. Thus he closed both eyes.
