असुर्या नाम ते लोका अन्धेन तमसावृताः । ताँस्ते प्रेत्याभिगच्छन्ति ये के चात्महनो जनाः ॥
asuryā nāma te lokā andhena tamasāvṛtāḥ / tāṃs te pretyābhigacchanti ye ke cātmahano janāḥ //
Plain EnglishSunless — those worlds are covered in blind darkness. Those who slay the self go there after death.
Layer 2 — What it means
Ātmahanaḥ — those who slay the self. Not murderers of other people. People who live as though the self were merely the body-mind: who identify completely with the physical, who have no knowledge of or orientation toward the Ātman. By slaying the self in this sense — denying its reality through the way they live — they enter worlds of blind darkness (andhena tamasāvṛtāḥ) after death.
This is the Upaniṣad's sharpest warning: the cost of living without any inquiry into the nature of the self. Not a moral failing but an epistemological one. It does not say these people are evil. It says they have not turned toward the light that is the subject of this entire text.
Reading this page will give you the concept clearly. But the Upanishads were not written to be understood the way you understand chemistry or history. They were written to point toward something you can only recognise in yourself. That recognition is not on this page. This page only clears the way.

Layer 2 — Philosophical meaning
Asuryā is parsed two ways: (1) sunless worlds, from a-negation + sūrya (sun); (2) worlds of the asuras (demonic beings), associated with darkness and ignorance. Both readings are found in the commentaries. Gambhirananda follows the first: sunless, because sūrya in the Upaniṣads consistently represents Brahman as revealed light — the sun that Brahman is hidden behind in verse 15 of this same text. The worlds without sun are the worlds without the recognition of Brahman. Śaṅkara's bhāṣya: the verse is not about post-mortem geography but about the result of living entirely within the limits of the body-mind identification — such a life, continued after death, continues in the same darkness.
