Lord Kṛṣṇa is describing how you become Kṛṣṇa conscious fully, in every step of your life. This verse we have been discussing last day, that raso 'ham apsu kaunteya. This glass of water, the taste, the juice of this water, is Kṛṣṇa. You cannot, when you are thirsty . . . this water given by God; there is no other replacement. If somebody offers me, "Instead of water, you drink gold," no, this water is required. The taste of the water is so nice that when I am thirsty, I require water. No manufacturer can create this taste of the water. Therefore, which is not possible to produce by any human being, that is God.
So raso 'ham apsu kaunteya. We can remember Kṛṣṇa, or God, when we drink water, because nobody can avoid drinking water. So the God consciousness is there. How can you forget? Raso 'ham apsu kaunteya prabhāsmi śaśi-sūryayoḥ. When there is some illumination, when there is some illumination . . .
(aside) You want to come here? I ask this . . .
(indistinct) . . . all right.
When there is some illumination, that illumination is also Kṛṣṇa. The original effulgence is brahma-jyoti. That is in the spiritual sky. This material sky is covered; therefore the nature of this material sky is darkness. Now, at night we are experiencing the real nature of this material world—it is darkness. Artificially, it is being illuminated by the sun, by the moon, by the electricity. Otherwise, it is darkness. So this illumination is God, we have to understand. This illumination.
Now, how this illumination is coming? Originally, in the spiritual sky, just like the sun has the shining force which we call sunshine, similarly in the . . . from the kingdom of God, there is a shining which is called brahma-jyoti. The brahma-jyoti is reflected by the sun; the moon is reflected by the sun. I mean to say, sun is reflection of brahma-jyoti, and moon is reflection of the sun. Everyone, you know, the stars, glittering stars, they are also reflection of the sun. Similarly, this electricity is also reflection of sun. The diamond, the jewels, everything, that is reflection of sun.
(aside) That's all right.
So Kṛṣṇa says, prabhāsmi śaśi-sūryayoḥ. Śaśi. Śaśi means the moon, and sūrya . . . sūrya means the sun. And in the spiritual world there is no need of sun and moon. Na tatra bhāsayate sūryo na śaśāṅko na pāvakaḥ (BG 15.6).
In the spiritual world there is no need of sun, there is no need of moon, there is no need of electricity. Because in the spiritual sky everything is illuminated, so there is no need. So we can remember God, or Kṛṣṇa, when you see some illuminating property.
Praṇavaḥ sarva-vedeṣu. When we chant Vedic mantra, oṁ tad viṣṇoḥ paramaṁ padaṁ sadā paśyanti sūrayaḥ (Ṛg-veda 1.22.20). Oṁ bhūr bhuvaḥ svaḥ tat savitur vareṇyaṁ bhargo devasya dhīmahi (Gāyatrī mantra).
Now, this oṁkāra, oṁ, that is the beginning. This oṁkāra is addressing. Just like we are addressing, "Hare Kṛṣṇa," this is also addressing, "O Harā, O Kṛṣṇa." This oṁkāra is also addressing. So this oṁkāra is Kṛṣṇa, is God. Praṇavaḥ sarva-vedeṣu śabdaḥ khe pauruṣaṁ nṛṣu (BG 7.8).
And śabda means sound. Whenever you hear some sound, you should know, "This is vibration of the transcendental sound." The sound which we are vibrating, that is pure spiritual sound. But any sound in the material world, that is reflection of that spiritual sound.
So when you hear sound, you can remember God. When you drink water, you can remember God. When you see some illumination, you can remember God. And when you chant some mantra, some hymn, that also you can remember God. So where you cannot remember God? Everywhere. This is Kṛṣṇa consciousness, God consciousness. Always, twenty-four hours, we can remember Kṛṣṇa. That remembrance means that Kṛṣṇa is with me. Kṛṣṇa is already with me, but as soon as we remember, that is factual.
