It has been explained in the previous verse that all desires on the mental platform become visible one after another. Sometimes, however, by the supreme will of the Supreme Personality of Godhead, the whole stockpile can be visible all at one time. In Brahma-saṁhitā (5.54) it is said, karmāṇi nirdahati kintu ca bhakti-bhājām. When a person is fully absorbed in Kṛṣṇa consciousness, his stockpile of material desires is minimized. Indeed, the desires no longer fructify in the form of gross bodies. Instead, the stockpile of desires becomes visible on the mental platform by the grace of the Supreme Personality of Godhead.
In this connection, the darkness occurring before the full moon, the lunar eclipse, can be explained as being another planet, known as Rāhu. According to Vedic astronomy, the Rāhu planet, which is not visible, is accepted. Sometimes the Rāhu planet is visible in the presence of full moonlight. It then appears that this Rāhu planet exists somewhere near the orbit of the moon. The failure of modern moon excursionists may be due to the Rāhu planet. In other words, those who are supposed to be going to the moon may actually be going to this invisible planetRāhu. Actually, they are not going to the moon but to the planet Rāhu, and after reaching this planet, they come back. Apart from this discussion, the point is that a living entity has immense and unlimited desires for material enjoyment, and he has to transmigrate from one gross body to another until these desires are exhausted.
(Srimad Bhagavatam------4:29:69------purport).

Just north of Ilāvṛta-varṣa—and going further northward, one after another—are three mountains named Nīla, Śveta and Śṛṅgavān. These mark the borders of the three varṣas named Ramyaka, Hiraṇmaya and Kuru and separate them from one another. The width of these mountains is 2,000 yojanas (16,000 miles). Lengthwise, they extend east and west to the beaches of the ocean of salt water. Going from south to north, the length of each mountain is one tenth that of the previous mountain, but the height of them all is the same.
In this regard, Madhvācārya quotes the following verses from the Brahmāṇḍa Purāṇa:
yathā bhāgavate tūktaṁ
bhauvanaṁ kośa-lakṣaṇam
tasyāvirodhato yojyam
anya-granthāntare sthitam
maṇḍode puraṇaṁ caiva
vyatyāsaṁ kṣīra-sāgare
rāhu-soma-ravīṇāṁ ca
maṇḍalād dvi-guṇoktitām
vinaiva sarvam unneyaṁ
yojanābhedato 'tra tu
It appears from these verses that aside from the sun and moon, there is an invisible planet called Rāhu. The movements of Rāhu cause both solar and lunar eclipses. We suggest that the modern expeditions attempting to reach the moon are mistakenly going to Rāhu.
(Srimad Bhagavatam------5:16:8------translation and purport).

On the upper chin of the śiśumāra is Agasti; on its lower chin, Yamarāja; on its mouth, Mars; on its genitals, Saturn; on the back of its neck, Jupiter; on its chest, the sun; and within the core of its heart, Nārāyaṇa. Within its mind is the moon; on its navel, Venus; and on its breasts, the Aśvinī-kumāras. Within its life air, which is known as prāṇāpāna, is Mercury, on its neck is Rāhu, all over its body are comets, and in its pores are the numerous stars.
(Srimad Bhagavatam------5:23:7------translation).

This chapter describes the planet Rāhu, which is 10,000 yojanas (80,000 miles) below the sun, and it also describes Atala and the other lower planetary systems. Rāhu is situated below the sun and moon. It is between these two planets and the earth. When Rāhu conceals the sun and moon, eclipses occur, either total or partial, depending on whether Rāhu moves in a straight or curving way.
Below Rāhu by another 1,000,000 yojanas are the planets of the Siddhas, Cāraṇas and Vidyādharas, and below these are planets such as Yakṣaloka and Rakṣaloka. Below these planets is the earth, and 70,000 yojanas below the earth are the lower planetary systems-Atala, Vitala, Sutala, Talātala, Mahātala, Rasātala and Pātāla. Demons and Rakṣasas live in these lower planetary systems with their wives and children, always engaged in sense gratification and not fearing their next births. The sunshine does not reach these planets, but they are illuminated by jewels fixed upon the hoods of snakes. Because of these shining gems there is practically no darkness. Those living in these planets do not become old or diseased, and they are not afraid of death from any cause but the time factor, the Supreme Personality of Godhead.
(Srimad Bhagavatam------5:24------summary).

Śrī Śukadeva Gosvāmī said: My dear King, some historians, the speakers of the Purāṇas, say that 10,000 yojanas (80,000 miles) below the sun is the planet known as Rāhu, which moves like one of the stars. The presiding deity of that planet, who is the son of Siṁhikā, is the most abominable of all asuras, but although he is completely unfit to assume the position of a demigod or planetary deity, he has achieved that position by the grace of the Supreme Personality of Godhead. Later I shall speak further about him.
(Srimad Bhagavatam------5:24:1------translation).

The sun globe, which is a source of heat, extends for 10,000 yojanas (80,000 miles). The moon extends for 20,000 yojanas (160,000 miles), and Rāhu extends for 30,000 yojanas (240,000 miles). Formerly, when nectar was being distributed, Rāhu tried to create dissension between the sun and moon by interposing himself between them. Rāhu is inimical toward both the sun and the moon, and therefore he always tries to cover the sunshine and moonshine on the dark-moon day and full-moon night.
As stated herein, the sun extends for 10,000 yojanas, and the moon extends for twice that, or 20,000 yojanas. The word dvādaśa should be understood to mean twice as much as ten, or twenty. In the opinion of Vijayadhvaja, the extent of Rāhu should be twice that of the moon, or 40,000 yojanas. However to reconcile this apparent contradiction to the text of the Bhāgavatam, Vijayadhvaja cites the following quotation concerning Rāhu; rāhu-soma-ravīṇāṁ tu maṇḍalā dvi-guṇoktitām. This means that Rāhu is twice as large as the moon, which is twice as large as the sun. This is the conclusion of the commentator Vijayadhvaja.
(Srimad Bhagavatam------5:24:2------translation and purport).

After hearing from the sun and moon demigods about Rāhu's attack, the Supreme Personality of Godhead, Viṣṇu, engages His disc, known as the Sudarśana cakra, to protect them. The Sudarśana cakra is the Lord's most beloved devotee and is favored by the Lord. The intense heat of its effulgence, meant for killing non-Vaiṣṇavas, is unbearable to Rāhu, and he therefore flees in fear of it. During the time Rāhu disturbs the sun or moon, there occurs what people commonly know as an eclipse.
The Supreme Personality of Godhead, Viṣṇu, is always the protector of His devotees, who are also known as demigods. The controlling demigods are most obedient to Lord Viṣṇu, although they also want material sense enjoyment, and that is why they are called demigods, or almost godly. Although Rāhu attempts to attack both the sun and the moon, they are protected by Lord Viṣṇu. Being very afraid of Lord Viṣṇu's cakra, Rāhu cannot stay in front of the sun or moon for more than a muhūrta (forty-eight minutes). The phenomenon that occurs when Rāhublocks the light of the sun or moon is called an eclipse. The attempt of the scientists of this earth to go to the moon is as demoniac as Rāhu's attack. Of course. their attempts will be failures because no one can enter the moon or sun so easily. Like the attack of Rāhu, such attempts will certainly be failures.
(Srimad Bhagavatam------5:24:3------translation and purport).

Below Rāhu by 10,000 yojanas (80,000 miles) are the planets known as Siddhaloka, Cāraṇaloka and Vidyādhara-loka.
It is said that the residents of Siddhaloka, being naturally endowed with the powers of yogīs, can go from one planet to another by their natural mystic powers without using airplanes or similar machines.
(Srimad Bhagavatam------5:24:4------translation and purport).

"I worship the primeval Lord, Govinda, who is always seen by the devotee whose eyes are anointed with the pulp of love. He is seen in His eternal form of Śyāmasundara, situated within the heart of the devotee." An exalted devotee, or mahātmā, who is rarely to be seen, remains fully conscious of Kṛṣṇa and constantly sees the Lord within the core of his heart. It is sometimes said that when one is influenced by evil stars like Saturn, Rāhu or Ketu, he cannot make advancement in any prospective activity. In just the opposite way, Prahlāda Mahārāja was influenced by Kṛṣṇa, the supreme planet, and thus he could not think of the material world and live without Kṛṣṇa consciousness. That is the sign of a mahā-bhāgavata. Even if one is an enemy of Kṛṣṇa, a mahā-bhāgavata sees him to be also engaged in Kṛṣṇa's service. Another crude example is that everything appears yellow to the jaundiced eye. Similarly, to a mahā-bhāgavata, everyone but himself appears to be engaged in Kṛṣṇa's service.
(Srimad Bhagavatam------7:4:37------purport).

When the demons got possession of the container of nectar, an extraordinarily beautiful young woman appeared before them. All the demons became captivated by the young woman's beauty and became attached to Her. Now, because the demons were fighting among themselves to possess the nectar, they selected this beautiful woman as a mediator to settle their quarrel. Taking advantage of their weakness in this regard, Mohinī, the incarnation of the Supreme Personality of Godhead, got the demons to promise that whatever decision She might give, they would not refuse to accept it. When the demons made this promise, the beautiful woman, Mohinī-mūrti, had the demigods and demons sit in different lines so that She could distribute the nectar. She knew that the demons were quite unfit to drink the nectar. Therefore, by cheating them She distributed all the nectar to the demigods. When the demons saw this cheating of Mohinī-mūrti, they remained silent. But one demon, named Rāhu, dressed himself like a demigod and sat down in the line of the demigods. He sat beside the sun and the moon. When the Supreme Personality of Godhead understood how Rāhu was cheating, He immediately cut off the demon's head. Rāhu, however, had already tasted the nectar, and therefore although his head was severed, he remained alive. After the demigods finished drinking the nectar, the Supreme Personality of Godhead assumed His own form. Śukadeva Gosvāmī ends this chapter by describing how powerful is the chanting of the holy names, pastimes and paraphernalia of the Supreme Personality of Godhead.
(Srimad Bhagavatam------8:9------summary).

Rāhu, the demon who causes eclipses of the sun and moon, covered himself with the dress of a demigod and thus entered the assembly of the demigods and drank nectar without being detected by anyone, even by the Supreme Personality of Godhead. The moon and the sun, however, because of permanent animosity toward Rāhu, understood the situation. Thus Rāhu was detected.
The Supreme Personality of Godhead, Mohinī-mūrti, was able to bewilder all the demons, but Rāhu was so clever that he was not bewildered. Rāhu could understand that Mohinī-mūrti was cheating the demons, and therefore he changed his dress, disguised himself as a demigod, and sat down in the assembly of the demigods. Here one may ask why the Supreme Personality of Godhead could not detect Rāhu. The reason is that the Lord wanted to show the effects of drinking nectar. This will be revealed in the following verses. The moon and sun, however, were always alert in regard to Rāhu. Thus when Rāhu entered the assembly of the demigods, the moon and sun immediately detected him, and then the Supreme Personality of Godhead also became aware of him.
(Srimad Bhagavatam------8:9:24------translation and purport).

The Supreme Personality of Godhead, Hari, using His disc, which was sharp like a razor, at once cut off Rāhu's head. When Rāhu's head was severed from his body, the body, being untouched by the nectar, could not survive.
When the Personality of Godhead, Mohinī-mūrti, severed Rāhu's head from his body, the head remained alive although the body died. Rāhu had been drinking nectar through his mouth, and before the nectar entered his body, his head was cut off. Thus Rāhu's head remained alive whereas the body died. This wonderful act performed by the Lord was meant to show that nectar is miraculous ambrosia.
(Srimad Bhagavatam------8:9:25------translation and purport).

Rāhu's head, however, having been touched by the nectar, became immortal. Thus Lord Brahmā accepted Rāhu's head as one of the planets. Since Rāhu is an eternal enemy of the moon and the sun, he always tries to attack them on the nights of the full moon and the dark moon.
Since Rāhu had become immortal, Lord Brahmā accepted him as one of the grahas, or planets, like the moon and the sun. Rāhu, however, being an eternal enemy of the moon and sun, attacks them periodically during the nights of the full moon and the dark moon.
(Srimad Bhagavatam------8:9:26------translation and purport).

Both parties in that fight were extremely angry at heart, and in enmity they beat one another with swords, arrows and varieties of other weapons.
There are always two kinds of men in this universe, not only on this planet but also in higher planetary systems. All the kings dominating planets like the sun and moon also have enemies like Rāhu. It is because of occasional attacks upon the sun and moon by Rāhu that eclipses take place. The fighting between the demons and demigods is perpetual; it cannot be stopped unless intelligent persons from both sides take to Kṛṣṇa consciousness.
(Srimad Bhagavatam------8:10:6-----translation and purport).
