"The material world, material life, means simply demands, increasing the demands. That is the modern way of life, increasing artificial demand and being frustrated. That is our life. But if you want satisfaction, not frustration, not bafflement, then increase your love for God. And the process is very simple, recommended in this age. You haven't got to perform any severe austerity, penance, or you have got to go to the forest or Himalayan mountain or you have to do this, that. Nothing. You be situated in your place, whatever you may be. But if you simply chant this mantra, Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare, you will gradually develop.
Your first, the first installment will be that your heart will be cleansed of all material contamination. Then you'll be situated on the brahma-bhūtaḥ stage. Oh, prasannātmā! Oh, joyfulness! Without being joyful, you cannot understand what is God. If your mind is disturbed always, you cannot meditate, neither you can understand what is God, what you are. It is impossible. Therefore we have to accept any process which can make me joyful. That is stated in the Śrīmad-Bhāgavatam. We have got... Simply we are not chanting by sentiment. We have got enough literature, philosophy, background. It is not that we are sentimentalist. But this is a fact, that if you simply... You do not require to read all this literature. If you can, it is very good, but if you have no time, simply chant these sixteen words, Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. Make an experiment. We are not charging anything. We are not cheating you, that 'Give me some fifty dollars or twenty dollars. I'll give you some secret mantra.' No. It is open. You can take. Everyone can take. Everyone. We are chanting. You can chant with us and practice it, and there is no hard and fast rules and regulation.
You can chant any way, anywhere. Whether you are in the college, whether you're on the street, whether you are sleeping, lying, or whatever, you can chant. Because God has given you this tongue and you can chant. And this Hare Kṛṣṇa mantra, a dog or cat cannot chant although he has got the tongue. So you have got the facility. By God's mercy you have got this facility to chant the holy name of God. If you think that Kṛṣṇa is Indian God's name, actually it is not Indian God's name. Kṛṣṇa never claims that He's Indian or Hindu. Most of you have read Bhagavad-gītā. He claims everyone as His son. Not only human society—the animal society, bird society, the beast society, the plant society, the aquatic society, all. Sarva-yoniṣu. Sarva means all. Yoni, yoni means species of life. Everyone, all living entities, Kṛṣṇa says. Kṛṣṇa must be... If He is God, He must claim that, that 'The material nature is their mother and I am their father.' So Kṛṣṇa is for everyone. Not that... Don't think that Kṛṣṇa is for the Indian or for the Hindus. No. Hare Kṛṣṇa, Hare Kṛṣṇa. This Kṛṣṇa is for everyone. For the human being, for the animals—everyone. So if you think that Kṛṣṇa is belonging to some particular country or religion, then you can chant your own way. If in your religion, in your scripture, there is any God's name, you can chant that also. Our only propaganda is that you increase your love of God. And the simple process is to chant this Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. There is no charge for it. There is no loss on your part. There is no inconvenience on your part. At any moment, at any place. There is no restriction. So why don't you take advantage of this great boon to the human society?"
