In material existence there are many regulative principles and formalities. If material existence is temporary or false, this does not mean that the spiritual world, although similar, is also false. That one's material body is false or temporary does not mean that the body of the Supreme Lord is also false or temporary. The spiritual world is real, and the material world is similar to it. For example, in the desert we sometimes find a mirage, but although the water in a mirage is false, this does not mean that there is no water in reality; water exists, but not in the desert. Similarly, nothing real is in this material world, but reality is in the spiritual world. The Lord's form and His abode—Goloka Vṛndāvana in the Vaikuṇṭha planets—are eternal realities.
(Srimad Bhagavatam-----7:15:61-----purport).

Here is a distinction between the Supreme Personality of Godhead and the living entities. Nityo nityānāṁ cetanaś cetanānām (Kaṭha Upaniṣad 2.2.13). According to the Vedic version, the Lord is the supreme eternal, the supreme living being. The difference between the Supreme Being and the ordinary living being is that when this material world is annihilated, all the living entities remain silent in oblivion, in a dreaming or unconscious condition, whereas the Supreme Being stays awake as the witness of everything. This material world is created, it stays for some time, and then it is annihilated. Throughout these changes, however, the Supreme Being remains awake. In the material condition of all living entities, there are three stages of dreaming. When the material world is awake and put in working order, this is a kind of dream, a waking dream. When the living entities go to sleep, they dream again. And when unconscious at the time of annihilation, when this material world is unmanifested, they enter another stage of dreaming. At any stage in the material world, therefore, they are all dreaming. In the spiritual world, however, everything is awake.
(Srimad Bhagavatam-----8:1:9-----purport).

Svāyambhuva Manu instructs that whatever exists, not only in the spiritual world but even within this material world, is the property of the Supreme Personality of Godhead, who is present everywhere as the Superconsciousness. As confirmed in Bhagavad-gītā (13.3), kṣetra-jñam cāpi māṁ viddhi sarva-kṣetreṣu bhārata: in every field—in other words, in every body—the Supreme Lord is existing as the Supersoul. The individual soul is given a body in which to live and act according to the instructions of the Supreme Person, and therefore the Supreme Person also exists within every body. We should not think that we are independent; rather, we should understand that we are allotted a certain portion of the total property of the Supreme Personality of Godhead.
(Srimad Bhagavatam-----8:1:10-----purport).

When the Lord's footstep exceeded the height of all the lokas, including Maharloka, Janaloka, Tapoloka and Satyaloka, His nails certainly pierced the covering of the universe. The universe is covered by the five material elements (bhūmir āpo 'nalo vāyuḥ kham (B.G.7:4). As stated in the śāstra, these elements are in layers, each ten times thicker than the previous one. Nonetheless, the nails of the Lord pierced through all these layers and made a hole penetrating into the spiritual world. From this hole, the water of the Ganges infiltrated into this material world, and therefore it is said, pada-nakha-nīra janita jana-pāvana (Daśāvatāra-stotra 5). Because the Lord kicked a hole in the covering of the universe, the water of the Ganges came into this material world to deliver all the fallen souls.
(Srimad Bhagavatam-----8:20:34-----purport).

These are the instructions of foolish gurus. In other words, because of the instructions of a foolish guru one remains perpetually in material existence and suffers its tribulations. But if one is intelligent enough to take instructions from the Supreme Personality of Godhead, as enunciated in Bhagavad-gītā or the Sāṅkhya philosophy of Kapiladeva, one can very soon attain liberation and be situated in his original position of spiritual life. The words nijaṁ padam are significant. The living entity, being part and parcel of the Supreme Personality of Godhead, has the birthright to a position in Vaikuṇṭhaloka, or the spiritual world, where there is no anxiety. Therefore, one should follow the instructions of the Supreme Personality of Godhead. Then, as stated in Bhagavad-gītā, tyaktvā dehaṁ punar janma naiti mām eti so 'rjuna: (B.G.4:9) after giving up one's body, one will return home, back to Godhead. The Lord lives in the spiritual world in His original personality, and a devotee who follows the instructions of the Lord approaches Him (mām eti). As a spiritual person, such a devotee returns to the Personality of Godhead and plays and dances with Him. That is the ultimate goal of life.
(Srimad Bhagavatam-----8:24:51-----purport).

"One who has unflinching devotion for the Personality of Godhead has all the good qualities of the demigods. But one who is not a devotee of the Lord has only material qualifications that are of little value. This is because he is hovering on the mental plane and is certain to be attracted by the glaring material energy." (S.B.5:18:12) Citizens under the guidance of a Kṛṣṇa conscious king will become devotees, and then there will be no need to enact new laws every day to reform the way of life in the state. If the citizens are trained to become devotees, they will automatically become peaceful and honest, and if they are guided by a devoted king advised by devotees, the state will not be in the material world but in the spiritual world. All the states of the world should therefore follow the ideal of the rule or administration of Mahārāja Ambarīṣa, as described here.
(Srimad Bhagavatam-----9:4:21-----purport).

"Devotees solely engaged in the devotional service of the Supreme Personality of Godhead, Nārāyaṇa, never fear any condition of life. The heavenly planets, liberation and the hellish planets are all the same to a devotee." (S.B.6:17:28) A devotee is always situated in the spiritual world. Therefore he does not desire anything. He is known as akāma, or desireless, because he has nothing to desire except to render transcendental loving service to the Supreme Personality of Godhead. Because Mahārāja Ambarīṣa was a most exalted devotee of the Lord, he trained his subjects in such a way that the citizens in his state were not interested in anything material, including even the happiness of the heavenly planets.
(Srimad Bhagavatam-----9:4:24-----purport).

Of course, this is the material side of strī-saṅgī, but the situation of Lord Rāmacandra is spiritual, for He does not belong to the material world. Nārāyaṇaḥ paro 'vyaktāt: Nārāyaṇa is beyond the material creation. Because He is the creator of the material world, He is not subject to the conditions of the material world. The separation of Lord Rāmacandra from Sītā is spiritually understood as vipralambha, which is an activity of the hlādinī potency of the Supreme Personality of Godhead belonging to the śṛṅgāra-rasa, the mellow of conjugal love in the spiritual world. In the spiritual world the Supreme Personality of Godhead has all the dealings of love, displaying the symptoms called sāttvika, sañcārī, vilāpa, mūrcchā and unmāda. Thus when Lord Rāmacandra was separated from Sītā, all these spiritual symptoms were manifested. The Lord is neither impersonal nor impotent. Rather, He is sac-cid-ānanda-vigraha (Bs. 5.1), the eternal form of knowledge and bliss.
(Srimad Bhagavatam-----9:10:11-----purport).

Lord Rāmacandra's grief at the news of Sītādevī's entering the earth is not to be considered material. In the spiritual world also there are feelings of separation, but such feelings are considered spiritual bliss. Grief in separation exists even in the Absolute, but such feelings of separation in the spiritual world are transcendentally blissful. Such feelings are a sign of tasya prema-vaśyatva-svabhāva, being under the influence of hlādinī-śakti and being controlled by love. In the material world such feelings of separation are only a perverted reflection.
(Srimad Bhagavatam-----9:11:16-----purport).

As explained above, when the feelings of love and transcendental bliss from the spiritual world are pervertedly reflected in this material world, they are certainly the cause of bondage. As long as men feel attracted to women in this material world and women feel attracted to men, the bondage of repeated birth and death will continue. But in the spiritual world, where there is no fear of birth and death, such feelings of separation are the cause of transcendental bliss. In the absolute reality there are varieties of feeling, but all of them are of the same quality of transcendental bliss.
(Srimad Bhagavatam-----9:11:17-----purport).

After giving up the body, the devotee who becomes perfect in devotional service enters that particular universe where Lord Rāmacandra or Lord Kṛṣṇa is engaged in His pastimes. Then, after being trained to serve the Lord in various capacities in that prakaṭa-līlā, the devotee is finally promoted to sanātana-dhāma, the supreme abode in the spiritual world. This sanātana-dhāma is also mentioned in Bhagavad-gītā (paras tasmāt tu bhāvo 'nyo 'vyakto 'vyaktāt sanātanaḥ (B.G8:20). One who enters the transcendental pastimes of the Lord is called nitya-līlā-praviṣṭa. To understand clearly why Lord Rāmacandra returned, it is mentioned herewith that the Lord went to that particular place where the bhakti-yogīs go. The impersonalists misunderstand the statements of Śrīmad-Bhāgavatam to mean that the Lord entered His own effulgence and therefore become impersonal. But the Lord is a person, and His devotees are persons. Indeed, the living entities, like the Lord, were persons in the past, they are persons in the present, and they will continue to be persons even after giving up the body. This is also confirmed in Bhagavad-gītā.
