Kṛṣṇa, He's the Supreme Personality of Godhead. We work because we need something, but what need He has? He is full. He's self-sufficient, but still, He comes. As it is stated, yadā yadā hi dharmasya glānir bhavati bhārata (BG 4.7): "As soon as there is discrepancies in the discharge of religious principle," abhyutthānam adharmasya, "and there is prominence of irreligiosity," tadātmānaṁ sṛjāmy aham, "at that time, I descend."
Why Kṛṣṇa descends? That is explained by Kṛṣṇa. He comes Himself, He sends His representative, He sends His son to reform. Kṛṣṇa or Kṛṣṇa's devotee or Kṛṣṇa's son . . . why Lord Jesus Christ sacrificed his life? Just to show that the human society must be God conscious. But unfortunately, people do not take care.
They are following, they are calling themselves as Christian, but they're not following the example of Lord Jesus Christ. But they should follow, everyone. A person in Kṛṣṇa consciousness, they also should follow what Kṛṣṇa's devotee and Kṛṣṇa . . . that is required.
So either Kṛṣṇa or His representative who come on this planet or in this world just to show example how you should live, how you should utilize your human form of life, they have nothing to gain. They are complete. Those who are coming from spiritual kingdom or kingdom of . . . they have no want. They haven't got to do anything. They are all perfect. But still, they do.
Similarly, those who want to be leader of the society, they should be ideal persons, they should be Kṛṣṇa conscious person. Then the whole world will be happy. Otherwise, these nonsense, simply by manipulating votes if they become leader, what they can do? They have no education. They have no training how to do good to the people. They cannot do. Only those who are devotees, those who are Kṛṣṇa conscious or God conscious, they can do actual benefit to the society. Others cannot do.
