Chapter 2: The Path of Knowledge · Verse 16

नासतो विद्यते भावो नाभावो विद्यते सतः |

उभयोरपि दृष्टोऽन्तस्त्वनयोस्तत्त्वदर्शिभिः ॥१६॥

nāsato vidyate bhāvo nābhāvo vidyate sataḥ |

ubhayorapi dṛṣṭo'ntastvanayostattvadārśibhiḥ ||16||

The unreal has no existence, and the real never ceases to be. The seers of truth have concluded the nature of both of these.

Synthesis

This is one of the most philosophically dense verses in the Gita and serves as the epistemological foundation for everything that follows. 'Asat' — the unreal, the impermanent — has no enduring being. 'Sat' — the real, the eternal — can never not-be. The Advaita tradition reads this as the clearest statement of the distinction between Brahman (pure existence, sat) and the phenomenal world (asat, or more precisely, apparently real but ultimately non-subsistent). For Ramanuja, both the individual souls and the material world are real but derivative — they have being only insofar as they participate in God's being. Madhva affirms the genuine reality of souls, world, and God as three distinct categories of sat. The Kashmir Shaivism perspective dissolves the dichotomy: both apparent and real are movements within one Consciousness. The practical import is immense: if you are grieving over something that is by nature impermanent, you are grieving over asat — the unreal. And you are overlooking sat — the eternal — which is the true ground of every being you love.

Advaita Vedanta/Adi Shankaracharya

This verse, Shankara writes, is the crown of the Gita's ontology. 'Asat' — the body, its states, its relationships — has no independent being; it is changing, dependent, and ultimately sublated by knowledge. 'Sat' — Brahman, pure consciousness-existence — never undergoes negation. The truth-seers (tattva-darshis) have perceived this distinction clearly and thus are freed from grief over the impermanent and from fear of the real's loss.

Personal Growth

Anxiety and grief are often rooted in treating impermanent things — status, relationships in their current form, youth, certainty — as if they were ultimate realities. Recognizing what is truly real versus what is transient frees you from unnecessary suffering.
