The Lord is explained here to be adhokṣaja, beyond the reach of all material calculation. Akṣaja means "the measurement of our senses," and adhokṣaja means "that which is beyond the measurement of our senses."
(Srimad Bhagavatam----3:19:25----purport).

Therefore, Śrīmad-Bhāgavatam (1.2.6) explains that one has to achieve real satisfaction (yayātmā suprasīdati), but ātmā—the body, mind and soul—all become completely satisfied only if one develops devotional service to the Absolute Truth. Sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje. Adhokṣaja means the Absolute Truth. If one can develop his unflinching love for the transcendental Supreme Personality of Godhead, that can give complete satisfaction, otherwise there is no possibility of satisfaction in the material world or anywhere else.
(Srimad Bhagavatam----4:4:28----purport).

Adhokṣaja means that which transcends the limits of sense perception or sensuous experience. The Lord is transcendental to our sense experience, but He reveals Himself to the sincere devotee.
(Srimad Bhagavatam----3:5:18----purport).

"If you are at all serious to understand that transcendental knowledge, then you must approach to a person who has experience of the Absolute Truth." Otherwise, it is not possible. If you think that "I shall realize by mental speculation the Absolute Truth, it is not possible." Because you are sub... I mean, you are fructified with only imperfections. Your senses cannot approach. Therefore Brahman is said, avan mānasa gocara. Avan mānasa gocara: "It is beyond, beyond the mental speculation." And there is another name of the Supreme Lord, Adhokṣaja. Adhokṣaja. Adhokṣaja means adhah-kṛtaḥ akṣajaṁ jñānaṁ yatra, "where our material senses are defeated." Our material senses are defeated. We are defeated in every respect. So it is not possible to realize the Absolute Truth if we do not find a person who is realized soul, who is absolute, who has understood. It doesn't matter who is he.
(Lecture on Bhagavad-Gita----4:34-38).

Sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje (S.B.1:2:6). Adhokṣaje. God's another name is Adhokṣaja. Adhokṣaja means that conquers all materialistic attempt to see God. Adhokṣaja. Akṣaja means experimental knowledge. You cannot understand God by experimental knowledge, no. You have to learn in a different way. That means by submissive auraloral (aural) reception and rendering transcendental loving service. Then you can understand God.
(Lecture on Bhagavad-Gita----6:6-12).

But because you are soul, spirit soul, part and parcel of God, you have got a particular duty. That is eternal duty. That eternal duty is described here, sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje (S.B.1:2:6). And adhokṣaja. Adhokṣaja, this Sanskrit word, is applicable to this Absolute Truth. Akṣaja, adhokṣaja. Akṣaja means experimental knowledge, things which you can perceive by your present senses. Just like you can touch. You can understand a thing by touching, if it is hard or soft, liquid or solid. You can smell, you can hear—so many sensual activities. So things which you can perceive by your sensual activities, they are called direct knowledge or knowledge by experiment. But which is beyond your experiment, that is called adhokṣaja. Adhokṣaja means beyond your sense perception. So God's another name is Adhokṣaja, means beyond our perception. You cannot understand God by directly seeing or directly smelling, or directly hearing, or directly tasting or touching. It is not possible at the present moment unless you are spiritually advanced, unless our seeing power is rectified or hearing power is modified.
(Lecture on Srimad Bhagavatam----1:2:5).
