In Caitanya-caritamrta, Krsnadasa Kaviraja Gosvami has said,
‘dvaite' bhadrabhadra-jnana, saba -- -- ‘manodharma'
‘ei bhala, ei manda' -- -- ei saba ‘bhrama'
Dvaite... In the material world, dvaite bhadrabhadra, "This is good, this is bad," it is all mental concoction. After all, it is material world. Either you become very expert in handling these material affairs, very big businessman, Mr. Ford, Mr. this and that, or so many things... [break] ...successful, what is the meaning of this "Successful, unsuccessful"? You have to die. You have to suffer from disease. Just like nowadays the flu is going on. Does it mean that a big man or a rich man will not suffer? When the disease is there, either you are big man or rich man or poor man or small man, everyone has to suffer. So long you will be in the material world, if you do not rectify yourself, suddha-sattva... Tapo divyam yena suddhyet sattvam. If you don't rectify your existence, then this janma-mrtyu-jara-vyadhi will go on. Then what is the good? Actually, there is no good. ‘Ei bhala, ei manda' -- -- ei saba ‘bhrama'.. It is simply mental concoction. So in the material world, even you become very expert to deal with your business very nicely, it is all useless.
Ko vartha apto 'bhajatam sva-dharmatah. If one does not become Krsna conscious, his so-called success in this material world or failure, they have no value. Rather, if by sentiment somebody comes to Krsna consciousness and if for a few days he chants Hare Krsna mantra, their success, in future at least, guaranteed.
So it is so nice thing. If you neglectfully chant, still there is success, but it will take some time. And if you chant very carefully, following the rules and regulations, then your success in this life is guaranteed. So we can make our choice, because always Krsna gives us the chance to make our choice. Yathecchasi tatha kuru: "Whatever you like, you can do." So I am repeating my spiritual master's order that "Don't wait for another life." That is a very risky, another life. Maybe I am given the chance of taking my birth in a good brahmana
family or a rich family, but there is chance of again being spoiled. As we see, there are so many rich men's sons. They have got all the opportunity of chanting Hare Krsna. They have no economic problem. But
he has no knowledge, he has no good advisor, he has no guru. So he is, he thinks that "I have got this money for nothing. Let me enjoy wine and women. Let me..." He becomes spoiled. So although he was given the
chance, sucinam srimatam gehe, janmaisvarya-sruta-sri. Although he was given the chance by nature's law, he spoils himself. So we should always think, It is all Krsna's mercy that we have got this opportunity.
So push this Krsna consciousness movement and enlighten them. Enlighten them. That is your service, actually service to one's country.
