So God is invisible, who? For the persons who has no eyes to see Him. Alakṣyam. Although He is everywhere: aṇḍāntara-stha-paramāṇu-cayāntara-stham (Bs. 5.35), idaṁ hi viśvaṁ bhagavān. This viśvam, this universe, is the transformation of the energy of Kṛṣṇa. Therefore . . . the energy is not different from the energetic. Therefore the whole world is Kṛṣṇa. Whole world is Kṛṣṇa. So we have to make our eyes. That eyes can be purified, as it is stated in the Brahma-saṁhitā, premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayanti (Bs. 5.38). Santaḥ, those who are saintly persons, those who have developed love for God, prema, that añjana, that ointment, who has smeared the ointment of love on the eyes . . .
That then . . . just like we apply sometimes ointment and surma . . . what is called in English, surma? This powder, something? Anyway . . . so when our eyes are cleansed we thinks clearly; similarly, if we apply the ointment of love of God on the eyes, then we can see God. Just like Arjuna, Kṛṣṇa, Kuntī is seeing. Others, they do not understand that Kṛṣṇa is the Supreme Personality of Godhead, but the Pāṇḍavas and the Pāṇḍavas' mother, they know that "Here is Kṛṣṇa, the Supreme Personality of Godhead." Alakṣyam. Just like Kṛṣṇa was exhibiting His Virat-rupa in the battle of of Kurukṣetra. Only Arjuna was seeing, nobody else.
So God reveals Himself to the devotee. Although . . . just like Prahlāda Mahārāja was seeing that Nṛsiṁha-deva has come, and his father, atheist father, he was challenging, "Where is your God?" So God is everywhere, but He is not visible to the nondevotee. But one who is devotee, he can see Him. Every . . . not only once. Premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva (Bs. 5.38). Sadaiva means always. He is seeing always Kṛṣṇa. That is the position of saintly person.
