Constancy in Self-knowledge, insight into the purpose of true knowledge — this is declared to be knowledge. Whatever is contrary to this is ignorance. Krishna concludes the famous enumeration by defining knowledge as these twenty qualities collectively, and everything opposite as ignorance.
Synthesis
Constancy in Self-knowledge and insight into the purpose of true knowledge constitute the culminating virtue. Shankara sees this as the apex of the knowledge-list — steady abidance in the realization that one is Brahman. Ramanuja reads it as unwavering conviction that the soul's nature is to serve and love God. The Bhakti tradition sees this constancy as the devotee's unshakeable faith in Krishna's promise. Madhva declares that constancy in Self-knowledge culminates in knowing the soul's real nature as eternally dependent on God, with all knowledge serving this understanding. Abhinavagupta sees this as the culmination: the continuous, unbroken recognition of one's nature as Shiva, with all other virtues being preparatory. Vallabha teaches that the purpose of true knowledge is to reveal God's presence in everything — the steady awareness that all is divine. Tilak identifies the practical purpose: knowledge must express itself in tireless selfless service. Vivekananda defines true knowledge as that which manifests as character — mere intellectual understanding without transformation is ignorance in disguise.

Shankara declares this the most important definition of knowledge in the Gita. Knowledge is not mere learning but the permanent establishment in Self-awareness through the cultivation of these twenty qualities. Anything other than this — however learned — remains ignorance.
