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.
If your knowledge . . . just like Janārdana suggested three processes: one by applying our senses, another by accepting knowledge from others, and another, rejection. Two ways. Or skepticism, make void. So this is out of frustration. So make the mind void: no more thinking. And knowledge by imperfect senses, that will always remain imperfect. And knowledge from others, that is real goal. But provided you receive that knowledge from the perfect.
As we have given several times the example, just like a child wants to know who is his father. Now if he searches out "Who is my father?" he asks everybody, "Are you my father? Are you my father? Are you my father?" he will have to go on searching. Then again if he asks his neighbor, "Who is my father?" the neighbor also may not know and may give him misinformation. So that is also not possible. But if he goes to his mother and his mother is sincere and perfect, she can give, "My dear boy, he is your father." That is perfect.
So neither by researching one can find out his father, neither by employing his imperfect senses. But if he receives the knowledge from the sincere mother, then the knowledge is perfect. And he has no other alternative to know who is his father except the source of a sincere mother. Similarly, the Bhāgavat says, acintyāḥ khalu ye bhāvā na tāṁs tarkeṇa yojayet: things which are beyond your power of realization, don't try to understand by your so-called logic and argument. All nonsense. All nonsense. Tarkaḥ apratiṣṭhaḥ. This process of argument and logic, gymnasium, is imperfect always. You cannot realize what is the ultimate goal of life.
