Krishna—this sound is transcendental. Krishna means the highest pleasure. All of us, every living being, seeks pleasure. But we do not know how to seek pleasure perfectly. With a materialistic concept of life, we are frustrated at every step in satisfying our pleasure because we have no information regarding the real level on which to have real pleasure.
We have to understand the fact that, we are not this body; we are consciousness. Not exactly consciousness, for consciousness is actually the symptom of our real identity: we are pure soul, now merged within this material body. Modern material science lays no stress on this; therefore the scientists are sometimes misled in their understanding of spirit soul. But spirit soul is a fact, which anyone can understand by the presence of consciousness. Any child can understand that consciousness is the symptom of the spirit soul.
Now the whole process we are trying to learn from the Bhagavad-gita (The Song of God) is how to bring ourselves to this level of consciousness. And if we act from the level of consciousness, then we may not be pushed again into the level of this bodily conception; and, if we can continue on that level, if we can continue to act in pure consciousness, then, at the end of this body we shall be free from material contamination, our spiritual life will be revived, and the ultimate result will be that in our next life, after leaving this body, we shall have our full, eternal spiritual life.
Even after the destruction of this body, consciousness is not destroyed. Rather, consciousness is transferred to another type of body and again makes us aware of the material conception of life. That is also described in the Bhagavad-gita. At the time of death, if our consciousness is pure, we can be sure that our next life will not be material—our next life will be spiritual. If our consciousness is not pure at the point of death, then, after leaving this body, we shall have to take another material body. That is the process which is going on. That is Nature’s law.
We have now a finite body. The body which we see is the gross body. It is just like a shirt and coat: within the coat there is a shirt, and within the shirt there is a body. Similarly, the pure soul is covered by a shirt and coat. The garments are the mind, intelligence and false ego. False ego means the misconception that I am matter, that I am a product of this material world. This misconception makes me localized.
For example, because I have taken my birth in India, I think myself Indian. Because I have taken my birth in America, I think myself American. But as pure soul, I am neither Indian nor American. I am pure soul. These others are designations. American, or Indian, or German, or Englishman; cat or dog, or bee or bat, man or wife: all these are designations. In spiritual consciousness we become free from all such designations. That freedom is achieved when we are constantly in touch with the supreme spirit, Krishna.
