Practicing Yoga in the Age of Quarrel

For example, one may have a hundred dollars, and if they are spent one after another, the next day it will come to zero. That is  vyaya , exhaustible. But Kṛṣṇa consciousness is not like that. If you cultivate this knowledge of Kṛṣṇa consciousness, then it will increase. That is certified by Lord Caitanya Mahāprabhu.  Ānandāmbudhi-vardhanam. Ānanda  means “pleasure,” “transcendental bliss,” and  ambudhi  means “ocean.” In the material world we see that the ocean does not increase. But if one cultivates Kṛṣṇa consciousness, then his transcendental bliss will simply increase.  Ānandāmbudhi-vardhanam.  And I shall always remind everyone that the process is very simple. Anyone can chant, anywhere, without taxation or loss, but the gain is very great.
Śrī Caitanya Mahāprabhu has explained this  kīrtana  movement in His  Śikṣāṣṭaka .  Śikṣā  means “instruction,” and  aṣṭaka  means “eight.” He has given us eight verses to help us understand this Kṛṣṇa consciousness movement, and I shall explain the first of these instructions. The Lord says,  ceto-darpaṇa-mārjanam : one should cleanse the heart. I have explained this several times, but it does not become monotonous. It is just like the chanting of Hare Kṛṣṇa; it does not become tiresome. Our students can chant the Hare Kṛṣṇa mantra twenty-four hours a day, and they will never get tired. They will continue to dance and chant. And anyone can try it; because it is not material, one will never get tired of chanting Hare Kṛṣṇa. In the material world, if one chants anything, any favorite name, for three, four, or ten times, he will get tired of it. That is a fact. But because Hare Kṛṣṇa is not material, if one chants this mantra, he will never get tired. The more one chants, the more his heart will be cleansed of material dirt and the more the problems of his life within this material world will be solved.
What is the problem of our lives? That we do not know. Modern education never gives enlightenment about the real problem of life. That is indicated in the  Bhagavad-gītā . Those who are educated and are advancing in knowledge should know what is the problem of life. This problem is stated in the  Bhagavad-gītā : one should always see the inconveniences of birth, death, old age, and disease. Unfortunately no one pays attention to these problems. When a man is diseased he thinks, “All right. Let me go to the doctor. He will give me some medicine, and I will be cured.” But he does not consider the problem very seriously. “I did not want this disease. Why is there disease? Is it not possible to become free from disease?” He never thinks that way. This is because his intelligence is very low-grade, just like that of an animal. An animal suffers, but it has no sense. If an animal is brought to a slaughterhouse and sees
