In this verse Śrī Kṛṣṇa is describing how we can become fully Kṛṣṇa conscious, in all stages of life. All living entities must drink water. The taste of water is so nice that when we are thirsty nothing but water seems to do. No manufacturer can create the pure taste of water. We can thus remember Kṛṣṇa or God when we drink water. No one can avoid drinking water every day of his life, so God consciousness is there – how can we forget? Similarly, when there is some illumination, that is also Kṛṣṇa. The original effulgence in the spiritual sky, the brahmajyoti, emanates from the body of Kṛṣṇa. This material sky is covered. The very nature of the material universe is darkness, which we experience at night. It is being artificially illuminated by the sun, by the reflected light of the moon, and by electricity. Where is this illumination coming from? The sun is being illumined by the brahmajyoti, or the bright effulgence of the spiritual world. In the spiritual world there is no need for sun, moon, or electricity because there, everything is illuminated by the brahmajyoti. On this earth, however, we can remember Kṛṣṇa whenever we see some illumination from the sun. When we chant the Vedic mantras which begin with oṁ, we can also remember Kṛṣṇa. Oṁ, like Hare Kṛṣṇa, is also an address to God, and oṁ is also Kṛṣṇa. Śabdaḥ means sound, and whenever we hear any sound we should know that it is a vibration of the original sound, the pure spiritual sound oṁ, or Hare Kṛṣṇa. Whatever sound we hear in the material world is but a reflection of that original spiritual sound oṁ. In this way when we hear sound, when we drink water, when we see some illumination, we can remember God. If we can do this, then when will we not remember God? This is the process of Kṛṣṇa consciousness. In this way we can remember Kṛṣṇa twenty-four hours a day, and in this way Kṛṣṇa is with us. Of course, Kṛṣṇa is always with us, but as soon as we remember this, His presence is factual and is felt. There are nine different processes for associating with God, and the first method of association is śravaṇam – hearing. By reading the Bhagavad-gītā we hear the speeches of Śrī Kṛṣṇa, which means that we are actually associating with Kṛṣṇa, or God. ... | If you’d like to read: www.biglink.to/onthewaytokrishna
