After returning from the spiritual kingdom, which he was able to visit personally along with Kṛṣṇa, Arjuna was very much astonished. He thought to himself that although he was only an ordinary living entity, by the grace of Kṛṣṇa it had been possible for him to see personally the spiritual world. Not only had he seen the spiritual world, but he had also personally seen the original Mahā-Viṣṇu, the cause of the material creation. It is said that Kṛṣṇa never goes out of Vṛndāvana. Vṛndāvanaṁ parityajya na pādam ekaṁ gacchati. Kṛṣṇa is supreme in Mathurā, He is more supreme in Dvārakā, and He is most supreme in Vṛndāvana. Kṛṣṇa's pastimes in Dvārakā are displayed by His Vāsudeva portion, yet there is no difference between the Vāsudeva portion manifested in Mathurā and Dvārakā and the original manifestation of Kṛṣṇa at Vṛndāvana. In the beginning of this book we have discussed that when Kṛṣṇa appears, all His incarnations, plenary portions and portions of the plenary portions come with Him. Thus some of His different pastimes are manifested not by the original Kṛṣṇa Himself but by His different portions and plenary portions of incarnation. Arjuna was therefore puzzled about how Kṛṣṇa went to see the Kāraṇārṇavaśāyī Viṣṇu in the spiritual world. This is fully discussed in the commentaries of Śrīla Viśvanātha Cakravartī Ṭhākur.
