Kṛṣṇa . . . Aṇḍāntara-stha paramāṇu-cayāntara-stham (BS 5.35). As Kṛṣṇa is being described, Viṣṇu, within this universe, so He is not only within the universe as Garbhodakaśāyī Viṣṇu; He is within your heart also. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61). And not only within your heart, but as many atoms are there, the composition of your body, in each atom He is there. Aṇḍāntara-stha paramāṇu-cayāntara-stham.
So Kṛṣṇa is everywhere. But why you cannot see? Antar-bahir-avasthitam (SB 1.8.18). Kṛṣṇa is within and without. If He is within every atom, then atoms are there, outside and inside. So antar-bahiḥ, He is situated. Anyone can see Him, but He cannot be seen to the undevotee, not devotee. He cannot be seen. Nāhaṁ prakāśaḥ sarvasya yoga-māyā-samāvṛtaḥ (BG 7.25). He is not exposed to everyone. He is simply exposed to the devotee. Premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayan . . . (BS 5.38). The nondevotee cannot see. Nāhaṁ prakāśaḥ sarvasya. Unless Kṛṣṇa agrees to be seen, you cannot see. It is not possible. You cannot force Him to be seen by You. No, that is not possible. Svayam eva sphuraty adaḥ (CC Madhya 17.136). He . . . When He likes, He'll be seen by you, not that you can force Him. You cannot say that "Now I am qualified. Kṛṣṇa must come, and I'll see Him." That is not possible. We are never qualified unless Kṛṣṇa agrees to be seen by you. This is the . . . Nāhaṁ prakāśaḥ sarvasya yoga-māyā-samāvṛtaḥ (BG 7.25): "Everyone cannot see Me." Yoga-māyā-samāvṛtaḥ: "I am covered, I am veiled, by the yoga-māyā." Yoga-māyā will not allow you to see, unless you are devotee.
Therefore Kṛṣṇa confirms this fact: bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ (BG 18.55). If you want to know Kṛṣṇa, God, as He is, then you must practice devotional life. Then He'll be seen. Bhaktyā mām . . . yāvān yaś cāsmi tattvataḥ. To know Kṛṣṇa ordinarily—"Oh, Kṛṣṇa was born in India, in Mathurā. He's the son of such and such, and He was very big man"—that is not tattvataḥ. Tattvataḥ means as He is, sac-cid-ānanda vigrahaḥ (BS 5.1). Anādir ādir govindaḥ sarva-kāraṇa-kāraṇam.
So for . . . To know Kṛṣṇa, there are so many Vedic literatures. So we have to know through the mercy of the spiritual master. Tad-vijñānārthaṁ sa gurum eva abhigacchet (MU 1.2.12). Everything is there, just like Kṛṣṇa is there in the Bhagavad-gītā, but people could not understand Kṛṣṇa. Now we are presenting Kṛṣṇa as it is, people are understanding. They are becoming devotee. So we have to go through the right channel. Then we'll know Kṛṣṇa. And as soon as you know Kṛṣṇa as He is, your life is successful. That is the aim and object of Kṛṣṇa consciousness movement—simply to help the people to know Kṛṣṇa. This is the only business.
