Yes. In the spiritual sky you will find happiness, real happiness. In the material sky there is no happiness. How it can be happiness, because the four things are there, janma-mṛtyu-jarā-vyādhi (BG 13.9)? If you think it is happiness in spite of your death, then you are a fool. You do not want to be a dead man, but you are forced to accept death. You do not want to become old man, but you are forced to accept. And these things, if you accept—happiness—that is your foolishness.
Vyādhi. Jarā-vyādhi, disease. If you are constantly suffering from various types of diseases and if you think that you are happy, that is another foolishness. Therefore Bhāgavata says, parābhavas tāvad abodha-jāto yāvan na jijñāsata ātma-tattvam (SB 5.5.5), that "All the foolish persons who are born foolish, all their activities are defeat for them unless they are enlightened to inquire about ātma-tattvam."
So in the modern education there is no department for inquiring about ātma-tattvam. And they are proud of advancement of learning. But Bhāgavata says, parābhava: "These are all defeat." They do not know what is ātmā, what is ātma-tattva. They are identifying, "I am this body." "I am Indian," "I am American," "I am Gujarati," "I am Bengali," "I am this," "I am that."
Yasyātmā-buddhiḥ kuṇape tri-dhātuke, sa eva go-kharaḥ (SB 10.84.13). Anyone who identifies himself with this body, he is nothing but ass and cow. And that is going on. We are fighting, nations and nations, community and community, religious party and religious party—because due to the misidentification of body.
Therefore Kṛṣṇa consciousness begins when one is above this bodily concept of life. Sarvopādhi-vinirmuktam (CC Madhya 19.170). These are upādhis, designations. So these Kṛṣṇa conscious boys and girls, they are no longer thinking that, "I am American," "I am Canadian," "I am French," "I am German." No. "I am Indian." No. They know certainly that, "I am part and parcel of Kṛṣṇa. I am eternally servant of Kṛṣṇa." And that is our real identity. That is Kṛṣṇa consciousness. They are no more interested to be identified as American or European. And this is knowledge. And this is mukti. If one is under the misconception that, "I am American," "I am Indian," then how there is mukti? There is no mukti. Mukti means svarupena avasthiti: to stay in his own constitutional position. That is called mukti.
