Pradyumna: Translation: "The younger brothers of Mahārāja Yudhiṣṭhira observed that the age of Kali had already arrived throughout the world and that the citizens of the kingdom were already affected by irreligious practice. Therefore they decided to follow in the footsteps of their elder brother." (SB 1.15.45)
Prabhupāda: This kalinā... We are reading kalinādharmeṇa. Kalinā adharma. The two are mixed together becomes one, a sandhi. Kalinādharmeṇa. So kali. Kali means quarrel, unnecessarily quarrel. Kali... Kalinā, "by the age of Kali." This is the age of Kali. There are four ages-Satya, Tretā, Dvāpara, Kali-degrading, gradual degrading. This nature's way is to degrade. That is the nature's way, time factor. Just like you construct a very nice house today, good looking, fresh, but by ages it will become old. Your body, my body, in youthhood it is very beautiful, and in due course of time it will be ugly like me. So this is the work of the time. Similarly, nature's way, there are four ages: Satya-yuga, Tretā-yuga, Dvāpara-yuga, Kali-yuga. Seasonal changes.
So in Satya-yuga, the religious principles are followed strictly, cent percent. That is called Satya-yuga. And Tretā-yuga, twenty-five percent reduced. That means seventy-five percent religious principles and twenty-five percent irreligious. And the Dvāpara-yuga, fifty-fifty: fifty percent religious and fifty percent irreligious. And the Kali-yuga, seventy-five percent irreligious and twenty-five percent religious, gradually reducing to nil—no more religion. Then finished. Then there will be devastation. Again Satya-yuga will begin. This is the way of change of Satya-yuga-Satya, Tretā, Dvāpara, Kali. The duration of Satya-yuga is about eighteen hundred thousand of years. Eighteen hundred thousands of years. Hundred thousand. Eighteen hundred. Similarly, Tretā-yuga, about twelve hundred thousands of years. Similarly, Dvāpara-yuga, eight hundred thousands of years. And Kali-yuga four hundred thousands of years. This is the beginning of Kali-yuga. Out of four hundred thousands of years, we have passed only 5,000 years. Not only 400,000, 432,000's of years. There is regular calculation in the Vedic śāstra. So out of that, we have passed 5,000 years. That Kali-yuga has begun just after the Battle of Kurukṣetra. So we have passed only 5,000 years of this Kali-yuga. There are still balance, 427,000's of years, still balance.
So the Kali's friends... Just like a man is known by his company. So Kali-yuga is the age of irreligion. Therefore, quarrel and fighting. Quarrel and fighting, communal fighting. Unnecessarily they will form a community, a group, all rascals, another group, another group of rascals, and they will fight unnecessarily. Just like this nationalism. This is simply group of rascals. That's all. Why rascal? Because irreligious, therefore rascal. So "Big, big, men, big, big scientist, big, big... Still, they are rascal?' Yes. Still, they are rascal. Why? Because irreligious. They do not know what is God. Therefore they are rascal. This is the only test. "Whether you know God?" "No, sir." "Then you are rascal." That's all. No more test. One test is sufficient: "Whether you know God?" Because this human life is meant for knowing God. This temple is meant for human being, not for the cats and dogs. So if you (do not) know God, then you are a rascal. You are exactly like the cats and dogs. That's all. This is the verdict. Now you can fight. "Why you are calling me cats and dogs?" But this is the... We are talking, following Kṛṣṇa, the great authority. But what Kṛṣṇa says, that is right. If you scrutinize by your logic, argument, philosophy, science, you will find that Kṛṣṇa is perfectly right. Therefore we accept Kṛṣṇa.
