So Kṛṣṇa is, in this sen . . . He's identified that Bhagavān. Bhagavān means that nobody can surpass His knowledge. Because I have already given the definition of bhagavān, that a personality who is in full all the opulences—wealth, strength, fame and knowledge, beauty and renunciation—He is God. You see? So . . . now, in this, at the present moment, when people are godless, I think, this definition is convincing. If you find out a personality that . . . one who has got in full all these opulences, He is God, then it will be very difficult to present an ordinary man as God. You see?
You will find that in the Bhagavad-gītā, when Arjuna was convinced that Kṛṣṇa is the Supreme Personality of Godhead . . . but because in future others will have doubt about Kṛṣṇa, he requested Kṛṣṇa that "Will You show me Your universal form?" And Kṛṣṇa agreed and showed him the universal form. That means in future any intelligent man accepting a so-called God may also ask him, "Just show something, that you are God." Without showing something, simply by false advertisement, one cannot be God.
So whole mistake is that we do not know what is God. We consider God may be just like one of us. No. The God who is controlling such a huge affairs of universal administration, He cannot be . . . He is superconscious. That is superconsciousness. Now, here, aśocyān anvaśocas tvaṁ prajñā-vādāṁś ca bhāṣase (BG 2.11).
Now, the whole living existence is a very subtle thing. Now, this body, this body made of earth, water, fire, air, sky, this gross body: and behind this, there is another, subtle body. That is mind, intelligence and ego. So when we give up this gross body, that subtle body carries me to another gross body. So when this, this body is lifeless, that body, subtle body, is not lifeless. Just like at night, when this gross body is asleep, the subtle body works—therefore we dream.
So subtle body carries to next life. And I have given in the Introduction that how one man changes his body. Yaṁ yaṁ vāpi smaran loke tyajaty ante kalevaram (BG 8.6).
Now, the subtle body, I mean to say, mind, intelligence and ego, when these three things, psychic life, is absorbed in a certain kind of thought, the dying man gets a similar body in the next life. The, that we shall come when we make progress in the study of Bhagavad-gītā. Just like the air passing over the rose tree carries the flavor of the rose, and the air passing over a filthy place carries the flavor of that filthy place—the air is pure, but because it is passing over certain condition, it carries the flavor—similarly, the mind, intelligence and ego carries the flavor of our present activities to the next life. That is the subtle mystery of transmigration of the soul from one body to another.
Now, if this, this life we purify just like rose, then next life we shall get a body which is full of flavor. If, if, if in this life if we practice devotion of God, then next life is to become the associate of God. That cintāmaṇi-prakara-sadmasu (Bs 5.29)
We are transferred to that planet. You see? These are simple things. The whole thing is in my hand. If I want to be degraded, I can prepare myself in this life for such degradation in the next life. And if we want to elevate ourself to the highest perfection of life, as to become one of the associates of God, we can prepare ourself like that.
You'll find in the . . . in the advanced chapters that yānti deva-vratā devān pitṝn yānti pitṛ-vratāḥ (BG 9.25).
