If you want to enter somebody's house, and if you see the signboard, "No admission without permission," you'll never go there, because you are civilized. But a cat and dog will enter. A child will enter.
Therefore these laws of dharma, or religious system, is meant for the civilized human being, not for the uncivilized cats and dogs. No. Therefore when a civilized man, so-called civilized man, has no knowledge of God, no knowledge of the laws of God, it is simply animal society, that's all. Dharmeṇa hīna paśubhiḥ samānāḥ. They are animals. They are not to be considered as human being. This is dharma. This is religion. You cannot violate the laws of God. You cannot disobey the laws of God. You cannot say that, "I do not know the laws of God." You must know. Just like a good citizen, you must know what is the law of the state. If you say in the court, "My lord, I did not know this law," that is not excuse. You'll not be excused. As a citizen, good citizen, you are expected. Similarly, we must know what is dharma, what is God. That is humanity.
So Kṛṣṇa says in the Bhagavad-gītā, yadā yadā hi dharmasya glānir bhavati bhārata tadātmānaṁ sṛjāmy aham (BG 4.7). Kṛṣṇa says, God says, that when there is too much disobedience in the matter of law of the Supreme Lord, adharma, adharmasya abhyutthānam . . . Godlessness, without any knowledge of God, without any knowledge of the God's order, that is called dharmasya glānir, discrepancies in the matter of discharging the order of God. Tadātmānaṁ sṛjāmy aham. At that time, God advents, or descends. He descends personally, He descends by His representative, by His son, or by His name also. Because they are all identical. God, His representative, His name, His form, His activities—everything in relationship to God, that is also God. This evening we are discussing.
