Actually, although we have got independence, we have got consciousness, we have got power of thinking, of understanding, but it is limited. Therefore we don't agree with one another. However I may be big philosopher, I may be very big philosopher, very logician, but as soon as another big logician, another big philosopher comes, he defeats me. That is the way. And every philosopher, every logician is trying to defeat your theory, as you are trying to defeat others' theories. This is going on.
So as Śrīman Janārdana said, the knowledge which you are searching in different ways, that is impossible to come to the conclusion. Because we are searching with . . . however I may accept this method or that method or that method, but accepting the method means employing my senses. But the senses are imperfect. Either I accept this or that, I have to work with my senses. There are no other instruments. So when senses are imperfect, so whatever method you accept, that will be imperfect.
Then which method will be perfect? That method will be perfect, as it is stated in the Bhagavad-gītā, mattaḥ smṛtir jṣānam apohanaṁ ca (BG 15.15). When Kṛṣṇa from within yourself will give you right direction, then you'll come to the ultimate destination. Otherwise, whatever . . . however a great philosopher, scientist or anything you may be, you'll simply hover on the material, mental plane. That's all.
So either you call perfect knowledge or you call happiness, anything, what you call, if you want to know the ultimate goal of your life perfectly, you have to follow a different method. A different method. That method is called avaroha-panthā. There are . . . all methods of acquiring knowledge can be divided into two groups. One group is called āroha-panthā, or research, inductive process, and another method is called deductive process, or avaroha-panthā. The knowledge coming from the supreme source, that is called avaroha-panthā, and the knowledge which is being sought after by using our imperfect senses, that is called āroha-panthā. Ascending process and descending process.
So by ascending process, we can never come to the real knowledge. That is not possible, because our senses are imperfect. How we can ascend? Just like people are trying to ascend to the higher planetary system, but the instrument, sputnik, itself is imperfect. How you can go there? You can go 25,000 miles, again come back. Punar mūṣiko bhava. So this is going on. Because we are imperfect in every respect, so therefore we have to receive knowledge from the perfect. That is the process, real process.
