O Arjuna, I give heat, and I withhold and send forth the rain. I am immortality, and I am also death personified. Both spirit and matter are in Me.
(BHAGAVAD-GITA-------9:19-------TRANSLATION).

I am all-devouring death, and I am the generating principle of all that is yet to be. Among women I am fame, fortune, fine speech, memory, intelligence, steadfastness and patience.
As soon as a man is born, he dies at every moment. Thus death is devouring every living entity at every moment, but the last stroke is called death itself. That death is Kṛṣṇa. As for future development, all living entities undergo six basic changes. They are born, they grow, they remain for some time, they reproduce, they dwindle, and finally they vanish. Of these changes, the first is deliverance from the womb, and that is Kṛṣṇa. The first generation is the beginning of all future activities.

The supreme authority and inconceivable power of the Supreme Personality of Godhead can be minutely studied from this verse. He is always unlimited. That means that He has no creation or end. He is, however, death (in the form of time), as described in Bhagavad-gītā. Kṛṣṇa says, "I am death. I take away everything at the end of life." Eternal time is also without beginning, but it is the creator of all creatures. The example is given of touchstone, which creates many valuable stones and jewels but does not decrease in power. Similarly, creation occurs many times, everything is maintained, and, after a time, everything is annihilated—but the original creator, the Supreme Lord, remains untouched and undiminished in power.

Dhruva Mahārāja was advised to stop fighting by his grandfather, who was concerned that Dhruva was adhering to a personal ambition to fight to annihilate the whole race of Yakṣas. In this verse, therefore, Svāyambhuva Manu seeks to eradicate the last tinge of false ambition in Dhruva by explaining the position of the supreme controller. The words mṛtyum amṛtam, "death and immortality," are significant. In Bhagavad-gītā the Lord says, "I am ultimate death, who takes away everything from the demons." The demons' business is to continually struggle for existence as lords over material nature. The demons repeatedly meet death after death and create a network of involvement in the material world. The Lord is death for the demons, but for devotees He is amṛta, eternal life.

(SRIMAD BHAGAVATAM------4:11:27-------PURPORT).

The Supreme Personality of Godhead is death personified to miscreants and the supreme beloved Lord to the devotees. In Bhagavad-gītā the Lord says, mṛtyuḥ sarva-haraś cāham: (B.G.10:34) "I am all-devouring death." Faithless unbelievers, who challenge the appearance of God, will be delivered by the Supreme Personality of Godhead when He appears before them as death. Hiraṇyakaśipu, for example, challenged the authority of the Supreme Personality of Godhead, and the Lord met him in the form of Nṛsiṁhadeva and killed him. Similarly, the planet earth saw Mahārāja Pṛthu as death personified, and she also saw him in the mood of anger personified. Therefore she began to tremble. One cannot challenge the authority of the Supreme Personality of Godhead in any circumstance. It is better to surrender unto Him and take His protection at all times.

One foolish scientist recently declared that eventually life will be made permanent through science. Some so-called scientists are also trying to manufacture living entities within the laboratory. Thus in one way or another everyone is busy denying the existence of the Supreme Personality of Godhead and rejecting the supreme authority of the Lord. However, the Lord is so powerful that He destroys everything in the form of death. As Kṛṣṇa says in Bhagavad-gītā (B.G.10:34), mṛtyuḥ sarva-haraś cāham: "I am all-devouring death." The Lord is just like death to the atheists, for He takes away everything they accumulate in the material world. Hiraṇyakaśipu, the father of Prahlāda, always denied the existence of the Lord, and he tried to kill his five-year-old boy due to the boy's unflinching faith in God. However, in due course of time the Lord appeared as Nṛsiṁhadeva and killed Hiraṇyakaśipu in the presence of his son.

(SRIMAD BHAGAVATAM------4:24:65-------PURPORT).

In Bhagavad-gītā the Lord clearly says, mṛtyuḥ sarva-haraś cāham: (B.G.10:34) "I am all-devouring death." Thus mṛtyu, or death, is the representative who takes everything away from the living entity who has accepted a material body. No one can say, "I do not fear death." This is a false proposition. Everyone fears death. However, one who seeks shelter of the Supreme Personality of Godhead can be saved from death. One may argue, "Does the devotee not die?" The answer is that a devotee certainly must give up his body, for the body is material. The difference is, however, that for one who surrenders to Kṛṣṇa fully and who is protected by Kṛṣṇa, the present body is his last; he will not again receive a material body to be subjected to death.
