Direct means sense perception. Just like we see so many things directly with our eyes; we touch with our hands; we smell by our nose. These are direct perception by our senses.
Another name of the Supreme Personality of Godhead is adhokṣajam. Akṣaja, akṣaja means direct perception. Direct means sense perception. Just like we see so many things directly with our eyes; we touch with our hands; we smell by our nose. These are direct perception by our senses. But bhagavantam, Bhagavān, is adhokṣajam. He is beyond direct perception. Adhokṣajam. Adhaḥ, you cannot reach there by direct perception. Just like I do not see God. Then what do you see? Your seeing power is very limited. Why don't you accept that? So He's not appreciable by limited senses. Therefore His name is adhokṣaja. Adhokṣaja. Sattvaṁ viśuddham. Sattvaṁ viśuddham. Sattva, goodness, sattva-guṇa, rajo-guṇa. That sattvam, or existence, His existence is adhokṣaja, beyond our sense perception, and viśuddham. Apāpa-viddham, as it is stated in the Īśopaniṣad, viśuddham. He is never touched by the material contamination. Viśuddham. Sattvaṁ viśuddhaṁ vasudeva-śabditam. Here, however good we may be, there is some material touch. But so far Bhagavān, the Supreme Personality of Godhead, is concerned, His existence is viśuddham. Therefore He's called paraḥ. Nārāyaṇaḥ paraḥ. Paraḥ means above this material world, transcendental.
