In plain words
So give up attachment to the body. This body is merely a plaything: you must use it as a tool and carry out the actions of duty. Man is entitled to action. The whole world rests on action alone. O Arjuna! I alone am the director of this whole drama of the world; I alone make everyone dance,” He said.
Meanwhile the Yādavas were all destroyed in feuds among themselves, born of ego. When Kṛṣṇa too gave up His body and went to His own abode, Arjuna sank into an ocean of grief. ‘Kṛṣṇa! All this time You have protected us in every way. Have You too gone and left us! Who is our refuge now?’ he lamented, weeping floods of tears. With nothing he could do, he set out on the journey back to Hastināpura. All Dvārakā had fallen into ruin. The Yādavas had all fallen. In such a tragic situation Arjuna could not think what to do. The moment he reached Hastinā, his mother: ‘My son! How is Gopāla?’ she would ask. What answer was he to give then? He asked himself this. But he could find no answer. He left Dvārakā, taking sixteen thousand Gopīs with him. But on the way forest dwellers surrounded them. Yet Arjuna had no strength to fight them. Arjuna, who in the Mahābhārata war had scattered the enemy armies with his volleys of arrows, could not that day lift even his Gāṇḍīva. Helpless: ‘Kṛṣṇa! Where has my strength gone?’ he lamented. ‘He who gave it has Himself taken it back,’ he answered himself. ‘Kṛṣṇa! Protect Your Gopīs Yourself,’ he prayed. Then Kṛṣṇa Himself protected them in every way. Arjuna brought those Gopīs safely to Hastinā.
As soon as Dharmarāja saw Arjuna coming with a downcast face, he suspected some calamity. ‘Arjuna! What is it, that you are so sad?’ he asked. ‘Brother, I will tell you everything in detail later,’ said Arjuna.
