Even a, a small bird, you'll find... You give a small bird some grains. You'll see like this: "Is there enemy? Somebody's coming. Somebody's killing me." So full of anxieties. This is the condition. This is the condition. So you cannot, you cannot be free from the anxiety, dehinaḥ.
Prahlāda Mahārāja says, sadā samudvigna-dhiyām. And why this anxiety? Now, asad-grahāt. Asad-grahāt: "Because he has accepted this temporary body." He is eternal. A living spirit is eternal, but he has been forced to accept this temporary body. This is my position. One should be conscious of his precarious position, that "I am eternal, but I am encaged in a temporary body which will not exist. However I may try to make it youthful by so many arrangement, but no..." The science cannot give you permanent life. That is not possible. You may be, may be proud of your scientific advancement of knowledge, but Bhagavad-gītā says that four things... Janma-mṛtyu-jarā-vyādhi-duḥkha-doṣānudarśanam (BG 13.9). "My dear sir, however you may make advancement in scientific knowledge, you cannot stop birth, you cannot stop death, you cannot stop old age, neither you can stop diseases." You see? So, so long we have got this body, so we must have anxieties. That is the law of nature. Now, here, here it is said that... Now let us finish that. Prahlāda Mahārāja said, sadā samudvigna-dhiyām: "My dear father, for persons who have accepted this temporary material body and is full of anxiety always, for them, my idea is that they should give up this materialistic life and surrender unto Hari." Hari means Bhagavān, the Supreme Lord. That is the way of getting out of... And actually, this is so. In the Bhagavad-gītā you'll find in the last instruction to Arjuna is: sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja: (BG 18.66) "This is the most confidential knowledge I am giving you because you are My friend and because I love you very much. Therefore this is My last word."
