kalim sabhajayanty arya
 guna jñah sara-bhaginah
yatra sankirtanenaiva
 sarva-svartho ’bhilabhyate
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Those who are actually advanced in knowledge are able to appreciate the essential value of this Age of Kali. Such enlightened persons worship Kali-yuga because in this fallen age all perfection of life can easily be achieved by the performance of sankirtana.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
It is stated here that among the four ages — Satya, Treta, Dvapara and Kali — Kali-yuga is actually the best because in this age the Lord mercifully distributes the highest perfection of consciousness, namely Krsna consciousness, very freely. The word arya has been defined by Srila Prabhupada as “one who is advancing spiritually.” The nature of an advanced person is to search for the essence of life. For example, the essence of the material body is not the body itself but the spirit soul that is within the body; therefore an intelligent person gives more attention to the eternal spirit soul than to the temporary body. Similarly, although Kali-yuga is considered to be an ocean of contamination, there is also an ocean of good fortune in Kali-yuga, namely the sankirtana movement. In other words, all of the degraded qualities of this age are completely counteracted by the process of chanting the holy names of the Lord. Thus it is stated in the Vedic language,
 
dhyayan krte yajan yajñais
 tretayam dvapare ’rcayan
yad apnoti tad apnoti
 kalau sankirtya kesavam
 
“Whatever is achieved in Satya-yuga by meditation, in Treta by offering ritual sacrifices and in Dvapara by temple worship is achieved in Kali-yuga by chanting the names of Lord Kesava congregationally.”
 
The Vedic process gradually lifts the conditioned entity out of the darkness of ahankara, or false identification with the gross material body, and brings him to the platform of self-realization, or aham brahmasmi, “I am spirit soul. I am eternal.” One has to make further progress to discover that although one is eternal, there is a superior eternal entity, who is the Lord Himself within one’s own heart and within every atom in the material universe. Beyond this second phase of self-realization there is the third and final stage of perfection, which is realization of Bhagavan, or the Supreme Personality of Godhead, in His own abode.
 
The Supreme Personality of Godhead is not primarily the superintendent of this world but rather the enjoyer of His own world, which is beyond the most fantastic dreams of the conditioned living entity. In other words, although the king or president of a country is ultimately the controller of the prison department, the king or president derives actual pleasure within his own palace and not in administering justice to the foolish prisoners. Similarly, the Lord appoints the demigods to administer the material creation on His behalf while He Himself personally enjoys the ocean of transcendental bliss in His own transcendental kingdom. Thus, realization of the Lord within His own kingdom is far superior to the primitive understanding that the Lord is the “creator” of the prison of the material world. This realization of Bhagavan begins with understanding that there are innumerable Vaikuntha planets in the spiritual sky and that on each of them a particular expansion of Narayana dwells with His innumerable devotees who are attached to that particular form. The central and chief planet in the spiritual sky is called Krsnaloka, and there the Personality of Godhead exhibits His supreme and original form of Govinda. As confirmed by Lord Brahma, govindam adi-purusam tam aham bhajami. Lord Brahma also states:
 
isvarah paramah krsnah
 sac-cid-ananda-vigrahah
anadir adir govindah
 sarva-karana-karanam
 
(Brahma-samhita 5.1)
 
Thus, love of Krsna and entrance into Krsna’s planet in the spiritual sky is the most supremely perfect and exalted status of life available anywhere, at any time, throughout the totality of existence. That perfection is available in Kali-yuga simply by chanting the holy names of God: Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare. Therefore every sane man, woman or child should deeply understand the unprecedented opportunity offered by Caitanya Mahaprabhu and seriously take up this chanting process. Only the most unfortunate and irrational person will neglect this transcendental opportunity.
