Janma-mṛtyu-jarā-vyādhi-duḥkha-dosanudarśanam (BG 13.9). We may think very . . . that we are very safe and we are making good advancement in economic development, but there is no solution for these four problems, as enunciated by Bhagavad-gītā, janma, mṛtyu, jarā, vyādhi. Oh, there is no solution for birth. There is so much attempt for birth control all over the world, but still, in every minute or in every second some percentage of population is increasing.
Janma, mṛtyu. Similarly, there are so many attempts to discover scientific measures to stop death, but it is not possible; death is taking place. Rather, in the present age, death is taking place earlier than in years before. Formerly people were living, say, hundred years, eighty years, ninety years, and nowadays a man is living, utmost, seventy years, sixty years. If a man lives for eighty years, then he is considered to be very . . .
But time will come, as we get information from Śrīmad-Bhāgavatam, that at the end of this age, Kali-yuga, if a man lives for twenty to thirty years he'll be considered as the grand old man. So practically we are not making any progress. And materially it is not possible to make any progress. It is . . . that is called māyā, illusion. We are actually not making any progress, but we are thinking that we are making progress. This is called spell of māyā.
But the real problem is that we should understand that this place is full of danger, and in the Bhagavad-gītā it is certified, this place, duḥkhālayam aśāśvatam (BG 8.15). This place is full of misery and aśāśvatam. Even if you accept, "Oh, let it be miserable. I don't mind. I shall remain here . . ." People say frankly that "We don't want any other world. We don't want . . . don't believe in it, heaven" or "We don't believe in Vaikuṇṭha. We want to make ourself happy in this world." They say.
But from authorities like Kṛṣṇa or Bhagavad-gītā, we understand that this place is meant for suffering. This is called duḥkhālayam aśāśvatam. Even if we agree to live in this miserable place . . . because everyone, we want to live. Nobody wants to die. Nobody wants to die. Suppose we are sitting here, and if there is some death signal, oh, we shall at once flee away from this place, if there is fire, because we do not want to die. That is a fact. So . . . but this place is certified by Kṛṣṇa as duḥkhālayam aśāśvatam (BG 8.15): "It is place of misery; at the same time, it is temporary." Temporary.
As today we . . . I entered in your country, Canada, for the first time, and the time limit was given there by the immigration that "You cannot live here or stay here more than this time," similarly, even if I think, "Oh, Canada is very nice place. Montreal is very nice place. Let me stay here," oh, the immigration department will not allow me to stay.
Similarly, if you think that, "This material world is very nice. Let me stay here," oh, the higher authorities . . . there are higher authori . . . just like there are authorities in the immigration department, similarly there are higher authorities in the management of these worldly affairs. Yamarāja, oh, he'll not allow you to stay. You have to change your body.
Actually a living entity is eternal, but the problem is that he is changing body. Just like either I may live at Canada or USA or India—I shall live somewhere—but nobody will allow me to stay. Except in my own country, nobody will allow me to stay for long time. Similarly, this is not your place. This material world is foreign country for you, this material world. We belong to the spiritual world. We belong to the world where life is eternal, where life is blissful, and where there is no ignorance.
Just like Kṛṣṇa's body is described in the Brahma-saṁhitā and other Vedic literature that īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ (Bs. 5.1). Sac-cid-ananda-vigrahaḥ means His body is made of spiritual eternity, sat; and cit, full of knowledge; and ānanda, and full of bliss. In the Vedānta-sūtra also, it is stated about the Supreme Personality of Godhead, or the Absolute Truth, as ānandamayo 'bhyāsāt: "By nature He is full of bliss, the Absolute Truth, Absolute Person."
You see the Kṛṣṇa's picture, ānanda-cinmaya-rasa-pratibhāvitābhiḥ (Bs. 5.37). He's enjoying in blissfulness. This Rādhā and Kṛṣṇa, this is enjoyment, but this enjoyment is not like here, the young boys and girls, they enjoy. It is not like that. Because here the ānanda is temporary, it is not eternal, but that ānanda, rādhā-kṛṣṇa-praṇaya-vikṛtiḥ, is eternally blissful. So Kṛṣṇa is canvassing everyone that, "You come to Me. Here also you will have this eternal ānanda, eternal blissfulness." You are after loving affairs, but here in this material world, actually there is no love. It is only lust. And even if we accept that this is love, it will not exist. It will be finished.
Therefore in Vedic literature we find that ramante yoginaḥ anante (CC Madhya 9.29): "Those who are yogīs, those who are transcendentalist . . ." They also . . . every one of us are seeking after pleasure, ānanda, but the yogīs, either these jñāna-yogī, dhyāna-yogī or karma-yogī or bhakta-yogī . . . there are different kinds of yogīs, but the yogī means the person who wants to connect himself with the eternal happiness. That is called yogī: one who is not satisfied with this temporary, material happiness.
