Śrīmad-Bhāgavatam 3.12.19

So Kṛṣṇa has... Bhagavantam. Here it is said, bhagavantam. The Supreme Personality of Godhead is Kṛṣṇa, but He is adhokṣajam, beyond our sense perception. Adhokṣaja. Adhah-kṛtaṁ akṣajaṁ jnānam. Our knowledge is limited within this sense perception. That's all. We can see so long the light is there. If the light is not there, then our seeing power is finished. Therefore it is limited. And Kṛṣṇa is beyond this limitation. Therefore His name is Adhokṣaja. Adhah-kṛtaṁ akṣajaṁ indriya-jnānaṁ yena. Akṣajaṁ jnānam means "knowledge acquired by sense perception." Akṣaja. Akṣa means "eyes," and ja means "generated." So I see this book because my eyes are seeing it is book. But as soon as the light is off, I cannot see where is the book and where is the table, where you are. Similarly, we cannot see at the present moment by the imperfect senses what is Kṛṣṇa. Therefore it is Kṛṣṇa's kindness that He has appeared before you in a manner by which you can see Him. This is Kṛṣṇa's mercy. Not that the atheistic philosophy, "They are worshiping Deity, some stone, some metal," not like that. He is adhokṣaja. We cannot see Kṛṣṇa with our present eyes, but we can see Him through the scripture. The "through the scripture" is that although we cannot see Him by our present imperfect senses, adhokṣaja, beyond our perception, still, we can see Him. How? Through the authorities. Through the authorities.
The same example, as I have given, that I do not know who is my father, but through the authority of mother, I can see him: "Here is my father." This is called authority seeing. If mother certifies that "My dear child, here is your father," that is the only certificate, authority, you can understand who is your father. Otherwise there is no... By experimental knowledge, by mental speculation, "He may be my father, he may be my father, he may be my father..." That you go on speculating for many millions of years. Still, you will not be able to understand who is your father. But if you take the authority of your mother, immediately you understand. That is, means, adhokṣaja. You cannot speculate what is God, but if you take the authority, then you can understand God. Otherwise it is not possible.
