The word bhūyaḥ indicates again and again, that is to say the process of creation, maintenance and annihilation is going on perpetually by the external energy of the Lord. He is the cause of everything. But the living beings, who are constitutionally the parts and parcels of the Lord and are forgetful of the sweet relation, are given a chance again to get rid of the clutches of the external energy. And to revive his (the living being's) consciousness, the revealed scriptures are also created by the Lord. Vedic literatures are the guiding directions for the conditioned souls so they can get free from the repetition of creation and annihilation of the material world and the material body.
(Srimad Bhagavatam----1:10:22----purport).

The Lord says in the Bhagavad-gītā, "This created world and material energy are under My control. Under the influence of prakṛti, automatically they are created again and again, and this is done by Me through the agency of My external energy."
(Srimad Bhagavatam----1:10:22----purport).

The whole material existence is full of problems, and thus the fear problem is always prominent. This is due to our association with the illusory energy of the Lord, known as māyā orexternal energy, yet all fear is vanished as soon as there is the sound of the Lord, represented by His holy name, as it was sounded by Lord Śrī Caitanya Mahāprabhu in the following sixteen words:
Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare
Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare
We can take advantage of these sounds and be free from all threatening problems of material existence.
(Srimad Bhagavatam----1:11:3----purport).

Being illusioned by the conditions of the external energy, one falsely thinks himself to be the served, but actually he is not served; he is servant of the senses like lust, desire, anger, avarice, pride, madness and intolerance. When one is in his proper senses by attainment of spiritual knowledge, he realizes that he is not the master of the material world, but is only a servant of the senses.
(Srimad Bhagavatam----1:12:6----purport).

Foolish persons, bewildered by the external energy of Viṣṇu, do not know that the ultimate goal of the progressive search after happiness is to get in touch directly with Lord Viṣṇu, the Personality of Godhead.
(Srimad Bhagavatam----2:1:19----purport).

The materialistic view of exploitation of the material resources is occasioned by the illusion of the external energy of the Lord, and as such, if anyone wants to realize the Supreme Truth by conceiving of the universal form of the Lord, he must cultivate the service attitude. Unless the service attitude is revived, the conception of virāṭ realization will have very little effect on the seer.
(Srimad Bhagavatam----2:1:26----purport).

Self-realization is, as it were, offering a fight for eternal life against the material struggle for existence, and therefore by the illusory grace of the external energy, the yogī or the devotee is faced with many allurements which can entangle a great fighter again in the bondage of material existence.
(Srimad Bhagavatam----2:1:39----purport).

The whole material creation, therefore, is one with and different from Nārāyaṇa, simultaneously, and this supports the acintya-bhedābheda-tattva philosophy of Lord Śrī Caitanya Mahāprabhu. Being an emanation from the glancing potency of Nārāyaṇa, the whole material creation is nondifferent from Him. But because it is the effect of His external energy (bahiraṅgā māyā) and is aloof from the internal potency (ātma-māyā), the whole material creation is different from Him at the same time.
(Srimad Bhagavatam----2:1:39----purport).

For a liberated person, all the enjoyments listed above are considered to be absolutely useless. Only those who are conditioned by the material modes of external energy are captivated by different types of material enjoyment. In other words, the transcendentalist has no material desires to be fulfilled, whereas the materialist has all types of desires to be fulfilled.
(Srimad Bhagavatam----2:3:9----purport).

All living entities in different statuses of life within the material creation, beginning from the first demigod, Brahmā, down to the small ant, are conditioned under the law of material nature, or the external energy of the Supreme Lord.
(Srimad Bhagavatam----2:3:11----purport).

Those who are in control of the external energy of the Lord, or in other words those who are in the material world, must first of all know how the external energy of the Lord is working under the direction of the Supreme Personality, and afterwards one may try to enter into the activities of His internal energy. The mundaners are mostly worshipers of Durgā-devī, the external energy of Kṛṣṇa, but they do not know that Durgā-devī is but the shadow energy of the Lord. Behind her astonishing display of material workings is the direction of the Lord, as confirmed in the Bhagavad-gītā (9.10). The Brahma-saṁhitā affirms that Durgā-śakti is working by the direction of Govinda, and without His sanction the powerful Durgā-śakti cannot move even a blade of grass.
(Srimad Bhagavatam----2:4:6----purport).

So all living entities, both in the conditioned state and in the liberated state, are maintained by the Almighty Supreme Lord. Such maintenance is effected by the Lord through His different expansions of Self and three principal energies, namely the internal, external and marginal energies. The living entities are His marginal energies, and some of them, in the confidence of the Lord, are entrusted with the work of creation also, as are Brahmā, Marīci, etc., and the acts of creation are inspired by the Lord unto them (tene brahma hṛdā). Theexternal energy (māyā) is also impregnated with the jīvas, or conditioned souls. The unconditioned marginal potency acts in the spiritual kingdom, and the Lord, by His different plenary expansions, maintains them in different transcendental relations displayed in the spiritual sky.
(Srimad Bhagavatam----2:4:7----purport).

This phenomenal world is impersonally the representation of Vāsudeva because the ingredients of its creation, their interaction and the enjoyer of the resultant action, the living being, are all produced by the external and internal energies of Lord Kṛṣṇa. This is confirmed in the Bhagavad-gītā (7.4-5). The ingredients, namely earth, water, fire, air and sky, as well as the conception of material identity, intelligence and the mind, are produced of the external energy of the Lord. The living entity who enjoys the interaction of the above gross and subtle ingredients, as set up by eternal time, is an offshoot of internal potency, with freedom to remain either in the material world or in the spiritual world.
(Srimad Bhagavatam----2:5:14----purport).

The Supreme Lord is the master of the external energy manifested by the three material modes, namely goodness, passion and ignorance, and as master of this energy He is ever unaffected by the influence of such bewildering energy.
(Srimad Bhagavatam----2:5:18----purport).

Factually, the living entities are not meant to be so conditioned by material energy, but due to their being affected by the false sense of lording it over the material energy, they come under the influence of such potency and thus become conditioned by the three modes of material nature. This external energy of the Lord covers up the pure knowledge of the living entities eternally existing with Him, but the covering is so constant that it appears that the conditioned soul is eternally ignorant. Such is the wonderful action of māyā, orexternal energy manifested as if materially produced.
(Srimad Bhagavatam----2:5:19----purport).

The material creation is something like a cloud in the unlimited sky. The real sky is the spiritual sky, eternally filled with the rays of the brahmajyoti, and a portion of this unlimited sky is covered by the mahat-tattva cloud of the material creation, in which the conditioned souls, who want to lord it against the will of the Lord, are put into play as they desire under the control of the Lord by the agency of His external energy.
(Srimad Bhagavatam----2:5:21----purport).

Seventy-five percent of the expansive radiation of the Lord is manifested in the spiritual sky (tripād-vibhūti), and twenty-five percent of His personal radiation comprehends the entire expansion of the material universes. This is also explained and stated in the Bhagavad-gītā (10.42). Thus the seventy-five percent expansion of His radiation is called His internal energy, whereas the twenty-five percent expansion is called the external energy of the Lord. The living entities, who are residents of the spiritual as well as the material expansions, are His marginal energy (taṭastha-śakti), and they are at liberty to live in either of the energies, external or internal.
(Srimad Bhagavatam----2:6:17----purport).

Tripād-vibhūti, or the seventy-five percent known as the internal potency of the Lord, is to be understood as the kingdom of God far beyond the material sky; and when we speak of pāda-vibhūti, or the twenty-five percent comprising His external energy, we should understand that this refers to the sphere of the material world. It is also said in the Padma Purāṇa that the kingdom of tripād-vibhūti is transcendental, whereas the pāda-vibhūti is mundane; tripād-vibhūti is eternal, whereas the pāda-vibhūti is transient.
(Srimad Bhagavatam----2:6:18----purport).

The Lord is described here as omnipotent by three energies (tri-śakti-dhṛk). So primarily His three energies are internal, marginal and external. This external energy is also displayed in the three modes of goodness, passion and ignorance.
(Srimad Bhagavatam----2:6:32----purport).

Even in material existence, one is merged in the existence of the Lord. No materialist can disentangle self from matter, for the self is merged in the external energy of the Lord.
(Srimad Bhagavatam----2:6:35----purport).

Since neither Lord Śiva nor you nor I could ascertain the limits of spiritual happiness, how can other demigods know it? And because all of us are bewildered by the illusory external energy of the Supreme Lord, we can see only this manifested cosmos according to our individual ability.
(Srimad Bhagavatam----2:6:37----purport).

The science of learning a subject matter seriously is different from the sentiments of fanatics. Fanatics or fools may consider the Lord's activities in relation with theexternal energy to be useless for them, and they may falsely claim to be higher participants in the internal energy of the Lord, but factually the Lord's activities in relation with the external energy and the internal energy are equally good. On the other hand, those who are not completely free from the clutches of the Lord's external energy should devoutly hear regularly about the activities of the Lord in relation with the external energy. They should not foolishly jump up to the activities of the internal energy, falsely attracted by the Lord's internal potential activities like His rāsa-līlā. The cheap reciters of the Bhāgavatam are very much enthusiastic about the Lord's internal potential activities, and the pseudodevotees, absorbed in material sense enjoyment, falsely jump to the stage of liberated souls and thus fall down deeply into the clutches of external energy.
(Srimad Bhagavatam----2:6:53----purport).

Some of them think that to hear about the pastimes of the Lord means to hear about His activities with the gopīs or about His pastimes like lifting the Govardhana Hill, and they have nothing to do with the Lord's plenary expansions as the puruṣāvatāras and Their pastimes of the creation, maintenance or annihilation of the material worlds. But a pure devotee knows that there is no difference between the pastimes of the Lord, either in rāsa-līlā or in creation, maintenance or destruction of the material world. Rather, the descriptions of such activities of the Lord as the puruṣāvatāras are specifically meant for persons who are in the clutches of the external energy. Topics like the rāsa-līlā are meant for the liberated souls and not for the conditioned souls. The conditioned souls, therefore, must hear with appreciation and devotion the Lord's pastimes in relationship with the external energy, and such acts are as good as the hearing of rāsa-līlā in the liberated stage. A conditioned soul should not imitate the activities of liberated souls. Lord Śrī Caitanya never indulged in hearing the rāsa-līla with ordinary men.
(Srimad Bhagavatam----2:6:53----purport).

Lord Śrī Kṛṣṇa, being the Supreme Personality of Godhead and fountainhead of all other incarnations, is the only independent person. He enjoys His pastimes by creation as He desires and gives them up to the external energy at the time of annihilation.
(Srimad Bhagavatam----2:8:23----purport).

The spirit soul is distinct from the material conception of his life, but he is absorbed in such a material conception because of being influenced by the external energy of the Lord, called ātma-māyā. This has already been explained in the First Canto in connection with Vyāsadeva's realization of the Supreme Lord and His external energy. The external energyis controlled by the Lord, and the living entities are controlled by the external energy—by the will of the Lord. Therefore, although the living entity is purely conscious in his pure state, he is subordinate to the will of the Lord in being influenced by the external energy of the Lord.
(Srimad Bhagavatam----2:9:1----purport).
