So Kṛṣṇa has got two kinds of existence: prakaṭa and aprakaṭa. Prakaṭa means when you see Kṛṣṇa personally. When Kṛṣṇa is present on this planet, everyone can see Kṛṣṇa. And actually, everyone saw. But only the devotees could understand that "Here is the Supreme Personality of Godhead." So that is called prakaṭa, "physically present." And there is another phase, which is called aprakaṭa, "not physically present." But that does not mean Kṛṣṇa is dead or God is dead. That does not mean. Prakaṭa or aprakaṭa, physically present or not present, it doesn't matter.
So after all, He is adhokṣaja. This word is used, adhaḥ. Adhaḥ means subdued. And Akṣa, akṣa means eyes or senses. Akṣaja. Ja means generated. So our senses are there—eyes, ears, hands, legs, nose, so many. Ten senses are there. So we are acquiring knowledge, generated. Knowledge is generated from the senses. But so long our senses are materially contaminated, we do not get real knowledge. We have to acquire knowledge through the senses, but unless our senses are purified, we do not have real knowledge. So we cannot appreciate or understand God, His form, His name, His quality, His pastime, His entourage, nothing of them we can understand by our these present material senses. That is not possible. Therefore His name is Adhokṣaja. Adhaḥ. Adhaḥ means cut (curbed) down. You cannot approach the Supreme by your these blunt material senses. That is not possible. Therefore His name is Adhokṣaja. Adhah-kṛta akṣaja-jñānaṁ yatra. The adhokṣaja means... Jñāna means experimental knowledge. Just like these modern scientists, they believe in experimental knowledge. But they are so rascal, in their own case, they will say, "Yes, we are trying. In future it will be successful." Why not experimental knowledge now? If you say that life is generated from matter... You are writing so many books and getting Nobel Prize. Why not by experimental knowledge prove that "Here are some matters and chemicals and here is life"? That they say, "We are trying." This is their escape. But actually, science means two things: observation and experiment. If you do not experiment practically in the laboratory, simply observation is not sufficient. That is not science. That is theory.
Anyway, this experimental knowledge is not very helpful in the matter of understanding the Supreme. Experimental knowledge there is, but not by these blunt senses. When the senses are purified, then that experimental knowledge, that means spiritual experimental knowledge, that is perfect. Therefore it is said adhokṣaja. And our Kṛṣṇa consciousness movement is to understand that Adhokṣaja. Adhokṣaja means who is beyond the perception of these material senses. This is our subject matter. Our subject matter is not anything material. Material is within the purview of my material senses. But our subject matter is beyond the senses. Adhokṣaja, therefore it is said. Adhokṣaja. Just like Kuntī and others. Kṛṣṇa was not present before their eyes. Kṛṣṇa has already gone to His abode. But still, it is said that ekānta-bhaktyā bhagavaty adhokṣaje. Adhokṣaje. The same word is used. But if you cannot see God now, how there can be ekānta-bhakti?
Ekānta-bhakti means unalloyed devotion. This is the secret of devotional life. Even God is not physically present, a devotee can be very much exalted by devotional service. That is the teaching of Lord Caitanya Mahāprabhu. Because the sahajiyās... Sahajiyā means persons who take things very easily, according to his sense perception, manufactured. They are called sahajiyās. But these Gauḍīya Vaiṣṇava, the devotees following the footprints of Śrī Caitanya Mahāprabhu, they are not sahajiyās; they are devotee of the Adhokṣaja. Beyond the sense perception, still, they are devotee. This is the secret of Gauḍīya Vaiṣṇava. Beyond the sense perception. Just like Gosvāmīs. They were living at Vṛndāvana. And what sort of living? Simply in separation and search. Caitanya Mahāprabhu also taught us like that. He was searching, "Where is Kṛṣṇa? Where is Kṛṣṇa?" and feeling separation. Just like you feel sometimes with your lover separation and you search, this is our process. Always feel separation from Kṛṣṇa and try to search out. This is ekānta. This is explained here, ekānta-bhaktyā bhagavaty adhokṣaje. Adhokṣaje, "He is beyond my perception. Still, my devotion is unalloyed." Not that "I cannot see where is God. Oh, what is devotion?" Just try to understand. It appears to be contradictory. Because foolish people say that "If you cannot see God, where is the question of devotion? You want to serve God, but if you cannot see God, then how you can serve?" Therefore, particularly this word is used, ekānta-bhaktyā bhagavaty adhokṣaje niveśitātmopararāma saṁsṛteḥ. That is the process.
So even though we cannot see God with our present eyes, but God is so merciful that He becomes present before us in a manner by which we can see Him. That is this vigraha, arcā-vigraha. God is beyond our sensual perception, adhokṣaja. But those who are neophyte, they may become atheist that "We cannot see God, that... How can I serve Him?" But those who are advanced, they can see God every moment, although physically others cannot see. The example is that Hiraṇyakaśipu and Prahlāda. Prahlāda is seeing God, but his father, he is asking, "Where is your God? Where is your God?" He was saying to the column, pillar: "Is your God there?" But he is seeing God there; he says, "Yes." So he became angry. He broke the column, and actually God came out.
