Bhāvam means nature also. Just like we call nature sva-bhāva, sva-bhāva. So mad-bhāvam . . . this is one nature, this material nature. This is also Kṛṣṇa's bhāvam, means Kṛṣṇa's nature. Nothing is beyond Kṛṣṇa, but this is external nature. Bhūmir āpo 'nalo vāyuḥ . . . (BG 7.4), bhinnā me prakṛtir aṣṭadhā. Bhinnā means separated energy. The energy is working. Although it is Kṛṣṇa's nature, still, it is separated nature. Just like I am speaking; it is being recorded. When it will be replayed, you will hear the same sound, but still, it is separated from me. Similarly, this material nature is also Kṛṣṇa's nature. Nothing is beyond Kṛṣṇa. There are two nature, the spiritual nature and material nature. So material nature means external energy, and spiritual nature means internal energy. And we, we are also spiritual nature, marginal. We can remain either in the material nature or in the spiritual nature. Therefore we are marginal nature. There are three natures: external, internal and marginal.
So, so long we are in the material nature, external nature, we are unhappy. This is the position. Just like a fish, when it is put into the land, it is unhappy, or death. Similarly, if you, the creature of the land, if you are put into the water, you are unhappy, and death. So because we belong to the spiritual nature . . . as it is explained by Kṛṣṇa, that this material nature is aparā. Aparā means inferior, not fit for us. Therefore we are unhappy. So long we shall remain in the material nature, we must be unhappy. Just like this body. This body is made of material nature, and we are within this body. Dehino 'smin yathā dehe kaumāraṁ yauvanaṁ jarā (BG 2.13). So long we have got this body, material body, we must be unhappy. First of all, we must try to understand why we are unhappy. We are unhappy because we are in this material body. And the . . . what is the unhappiness? It is ending in four principles: janma-mṛtyu-jarā-vyādhi (BG 13.9). To take birth and again to die, and so long we live we must suffer from some disease and we must become old. Plain truth.
Therefore intelligent person must be aware of the miserable condition of this material existence and try to get out of it. Is there any doubt? Eh? This is the fact. So our only business is how to get out of this material existence. That is our only business—not that how we can adjust things here and become happy. That is called karmī, fools. It is a fact that so long you'll be here in this material world, however you may try to adjust things to become happy, it will be never possible. It will be never possible. They are trying to be materially happy in the Western world. They do not know actually what is happiness, but material happiness means sex life. So sex life they are every day enjoying. And still, they go to the naked dance to see if there is happiness. Why there will be happiness? There cannot be any happiness. But this is adjustment. They are trying this way or that way. That's all.
