These verses and purports are describing what happened after the departure of Lord Krsna(similar things could be said of when Srila Prabhupada also left)
SB 1.14.5- In course of time it came to pass that people in general became accustomed to greed, anger, pride, etc. Mahārāja Yudhiṣṭhira, observing all these omens, spoke to his younger brother.
PURPORT
Such a pious king as Mahārāja Yudhiṣṭhira at once became perturbed when there were such inhuman symptoms as greed, anger, irreligiosity and hypocrisy rampant in society. It appears from this statement that all these symptoms of degraded society were unknown to the people of the time, and it was astonishing for them to have experienced them with the advent of the Kali-yuga, or the age of quarrel.
…When the Lord, however, appears in His person as Lord Śrī Kṛṣṇa, His other plenary portions also join in Him by His inconceivable potency called yogamāyā, and thus the Lord Kṛṣṇa of Vṛndāvana is different from the Lord Kṛṣṇa of Mathurā or the Lord Kṛṣṇa of Dvārakā. The virāṭ-rūpa of Lord Kṛṣṇa is also different from Him, by His inconceivable potency. The virāṭ-rūpa exhibited on the Battlefield of Kurukṣetra is the material conception of His form. Therefore it should be understood that when Lord Kṛṣṇa was apparently killed by the bow and arrow of the hunter, the Lord left His so-called material body in the material world. ..That the Lord left His body means that He left again His plenary portions in the respective dhāmas (transcendental abodes), as He left His virāṭ-rūpa in the material world.
SB 1.14.11–The left side of my body, my thighs, arms and eyes are all quivering again and again. I am having heart palpitations due to fear. All this indicates undesirable happenings.
PURPORT–Material existence is full of undesirables. Things we do not want are forced upon us by some superior energy, and we do not see that these undesirables are under the grip of the three modes of material nature. When a man’s eyes, arms and thighs all quiver constantly, one must know that something is going to happen which is undesirable.
(More Verses)…Just see, O Bhīma, how the she jackal cries at the rising sun and vomits fire, and how thedog barks at me fearlessly.
O Bhīmasena, tiger amongst men, now useful animals like cows are passing me on my left side, and lower animals like the asses are circumambulating me. My horses appear to weep upon seeing me…Just see how the smoke encircles the sky…
…It appears that the earth and mountains are throbbing. Just hear the cloudless thunder and see the bolts from the blue… [Hawaii is now blowing her lid with volcanos]
The Deities seem to be crying in the temple, lamenting and perspiring. They seem about to leave. All the cities, villages, towns, gardens, mines and hermitages are now devoid of beauty and bereft of all happiness. I do not know what sort of calamities are now awaiting us.
(I personally have seen deities in iskcon temples that appeared very very sad)
SB 8.5.23 purport–
SB(12.3.51):kaler doṣa-nidhe rājann asti hy eko mahān guṇaḥ kīrtanād eva kṛṣṇasya
mukta-saṅgaḥ paraṁ vrajet
This age of Kali is full of unlimited faults. Indeed, it is just like an ocean of faults (doṣa-nidhi). But there is one chance, one opportunity. Kīrtanād eva kṛṣṇasya mukta-saṅgaḥ paraṁ vrajet: simply by chanting the Hare Kṛṣṇa mantra, one can be freed from the contamination of Kali-yuga and, in his original spiritual body, can return home, back to Godhead. This is the opportunity of Kali-yuga.
When Kṛṣṇa appeared, He gave His orders, and when Kṛṣṇa Himself appeared as a devotee, as Śrī Caitanya Mahāprabhu, He showed us the path by which to cross the ocean of Kali-yuga. That is the path of the Hare Kṛṣṇa movement. When Śrī Caitanya Mahāprabhu appeared, He ushered in the era for the saṅkīrtana movement. It is also said that for ten thousand years this era will continue. This means that simply by accepting the saṅkīrtana movement and chanting the Hare Kṛṣṇa mahā-mantra, the fallen souls of this Kali-yuga will be delivered. After the Battle of Kurukṣetra, at which Bhagavad-gītā was spoken, Kali-yuga continues for 432,000 years, of which only 5,000 years have passed. Thus there is still a balance of 427,000 years to come. Of these 427,000 years, the 10,000 years of the saṅkīrtana movement inaugurated by Śrī Caitanya Mahāprabhu 500 years ago provide the opportunity for the fallen souls of Kali-yuga to take to the Kṛṣṇa consciousness movement, chant the Hare Kṛṣṇa mahā-mantra and thus be delivered from the clutches of material existence and return home, back to Godhead.
