Srimad-Bhagavatam Lectures

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 Kṛṣṇa gives us the chance to make our choice.

Lecture on SB 1.7.20-21 -- Vrndavana, September 17, 1976:

Dvaite . . . In the material world, dvaite bhadrābhadra, "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, śuddha-sattva . . . Tapo divyaṁ yena śuddhyet sattvam (SB 5.5.1). If you don't rectify your existence, then this janma-mṛtyu-jarā-vyādhi will go on (BG 13.9). Then what is the good? Actually, there is no good. 'Ei bhāla, ei manda'—ei saba 'manodharma'. 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 vārtha āpto 'bhajatāṁ sva-dharmataḥ. If one does not become Kṛṣṇa conscious, his so-called success in this material world or failure, they have no value. Rather, if by sentiment somebody comes to Kṛṣṇa consciousness, and if for a few days he chants Hare Kṛṣṇa 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 Kṛṣṇa gives us the chance to make our choice. Yathecchasi tathā kuru (BG 18.63): "Whatever you like, you can do." So my request . . . It is my duty, because you have accepted me as your spiritual master. 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 brāhmaṇa 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 Kṛṣṇa. They have no economic problem. Father's property, immense property he has got. So he can . . . he has no anxiety for economic problems. That is a chance. To take birth in a rich family means he has no economic problem. Because for economic problem we see nowadays people are pulling on ṭhelā, a rickshaw, for two breads.(?) Because he is condemned to take such life, to work like an ass, like an animal. We see, practically.
