Thus, this most secret of scriptures has been spoken by Me, O sinless one. Knowing this, one becomes wise and fulfilled, O Bhārata.

Conclusion of chapter 15. It is described as guhya-tamam — the most secret, the most hidden. It is a śāstra (teaching text), but of the deepest kind.

The result of knowledge: buddhimān — wise, endowed with buddhi (higher intellect), and kṛta-kṛtyaḥ — fulfilled in duties, one who has done all that needs to be done. The human task is complete when the Puruṣottama is known. Arjuna is called anagha — sinless, without defect — and bhārata — descendant of Bharata.
