In plain words
We must think of Kṛṣṇa and Arjuna as the form of the jīva and Īśvara. Now, delusion came upon Arjuna too, you see, when he entered the battlefield. “Having killed so many kinsmen, friends and sons of my teachers, how am I to bear it! My eyes are reeling. Now, losing no more time, off to the heavens!” he said to Kṛṣṇa. Delusion came over him merely at the sight of his kinsmen and friends. This delusion is bound up with the sense of 'mine'. This sense of 'mine' is joined to attachment. This delusion arose from attachment and the feeling of 'mine' alone. When delusion of this kind arose, what did Kṛṣṇa tell Arjuna? ‘Arjuna! As long as delusion remains, you cannot see Brahman. You cannot reach Brahman,’ He said, and turned him away from delusion. He rooted out his fear. He brought the principle of Brahman to light. Only then did Arjuna, who had been abject, take shape as a steadfast man, a hero. Today the jīvas, who are Arjuna's representatives, are sinking into a kind of Ajñāna, merely through delusions and abjectness. They are forgetting their duty. They are losing the truth that is their humanness. With ceaseless toil, constant anxieties, endless desires and anguish he cannot understand, man scrambles to gain a form that cannot be gained: how can Śānti come to him? To recognise this formless, attributeless principle, which is eternal Satya, we must put delusion far from us. To put this delusion far from us, it is most necessary that we put everything into practice. This very delusion has come to be called ‘moha’. This moha arises only from the guṇas. The guṇas are imagined. Seeing this world, which is like a scene in a dream, fears and delusions of a kind keep arising. All of these are nothing but imaginings of what is seen! ‘Viśvaṃ darpaṇa dṛśyamānanagarī’, they have said. This whole universe appears merely as a reflection seen in a mirror. It appears in the mirror, but it has no connection with the mirror. It is visible to the eye, but it has no connection at all with the eye. The eyes always remain witnesses. The eyes are able to see all sights.
