Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 5


श्रीभगवानुवाचएते घोरा महोत्पाता द्वार्वत्यां यमकेतव: ।मुहूर्तमपि न स्थेयमत्र नो यदुपुङ्गवा: ॥ ५ ॥


śrī-bhagavān uvācaete ghorā mahotpātādvārvatyāṁ yama-ketavaḥmuhūrtam api na stheyamatra no yadu-puṅgavāḥ


The Supreme Personality of Godhead said: O leaders of the Yadu dynasty, please note all these terrible omens that have appeared in Dvārakā just like the flags of death. We should not remain here a moment longer.


Śrīla Viśvanātha Cakravartī Ṭhākura has given a great amount of evidence from the Vedic literatures proving that the humanlike form of the Personality of Godhead and His holy name, abode, paraphernalia and associates are all eternal, spiritual manifestations without any tinge of material contamination. (See Appendix). In this regard the ācārya has further explained that because the living entities must suffer the reactions to their sinful activities, the Lord arranges for them to be punished during the Kali-yuga. In other words, it is not Lord Kṛṣṇa’s desire that conditioned souls be sinful and suffer, but since they are already sinful, the Lord creates an appropriate age during which they can experience the bitter fruits of irreligiosity. Since Lord Kṛṣṇa personally establishes religious principles in His various appearances in this material world, at the end of Dvāpara-yuga religion on the earth was overwhelmingly powerful. All the significant demons had been killed; the great sages, saints and devotees had been greatly encouraged, enlightened and fortified; and there was little scope for irreligion. Had Lord Kṛṣṇa ascended to the spiritual sky in His spiritual body before the eyes of the world, it would have been very difficult for Kali-yuga to flourish. Lord Kṛṣṇa left the world in exactly that way during His appearance as Rāmacandra, and hundreds of thousands of years later, hundreds of millions of pious persons still discuss this wonderful pastime of the Lord. To pave the way for Kali-yuga, however, Lord Kṛṣṇa left this world in a way that puzzles those who are not His staunch devotees. The eternal form of the Lord is described throughout Vedic literature, and His eternal form constitutes the highest understanding of the Absolute Truth according to all great ācāryas, including Śaṅkarācārya and Caitanya Mahāprabhu. Yet although Lord Kṛṣṇa’s eternal, spiritual form is a realized fact for advanced devotees, for those who are weak in Kṛṣṇa consciousness the inconceivable pastimes and plan of the Lord are sometimes hard to appreciate properly.
