The different forms of the living entities are different dresses offered by the illusory, external energy of the Lord according to the modes of nature the living being desires to enjoy. The external, material energy is represented by her three modes, namely goodness, passion and ignorance. So even in the material nature there is a chance of an independent choice by the living entity, and according to his choice the material energy offers him different varieties of material bodies. There are bodies, 1,100,000 worms and reptiles, 1,000,000 forms of birds, together there are 8,400,000 varieties of bodies in different planets of the universe, and the living entity is traveling by so many transmigrations according to different modes of enjoying spirit within himself. Even in one particular body the living entity changes from childhood to boyhood, from boyhood to youth, from youth to old age and from old age to another body created by his own action. The living entity creates his own body by his personal desires, and the external energy of the Lord supplies him the exact form by which he can enjoy his desires to the fullest extent.
(Srimad Bhagavatam----2:9:2----purport).

The whole situation there is one of freedom from the illusory manifestation of the external energy. Although illusory energy is also part and parcel of the Supreme Lord, illusory energy is differentiated from the Lord. The illusory energy is not, however, false, as claimed by the monist philosophers. The rope accepted as a snake may be an illusion to a particular person, but the rope is a fact, and the snake is also a fact. The illusion of water on the hot desert may be illusion for the ignorant animal searching for water in the desert, but the desert and water are actual facts. Therefore the material creation of the Lord may be an illusion to the nondevotee, but to a devotee even the material creation of the Lord is a fact, as the manifestation of His external energy. But this energy of the Lord is not all. The Lord has His internal energy also, which has another creation known to be the Vaikuṇṭhalokas, where there is no ignorance, no passion, no illusion and no past and present. With a poor fund of knowledge one may be unable to understand the existence of such things as the Vaikuṇṭha atmosphere, but that does not nullify its existence. That spacecraft cannot reach these planets does not mean that there are no such planets, for they are described in the revealed scriptures.
(Srimad Bhagavatam----2:9:10----purport).

A conditioned soul is instrumental in the hands of the external energy, guṇa-mayī māyā, or the illusory energy of the Lord, and in the liberated stage the living entity is instrumental to the will of the Personality of Godhead directly.
(Srimad Bhagavatam----2:9:29----purport).

So the identity of the self as being unconnected with the Supreme Self, the Lord, is also illusion, and the false claim "I am the Supreme" is the last illusory snare of the same māyā, or the external energy of the Lord.
(Srimad Bhagavatam----2:9:34----purport).

The Lord is situated in the hearts of all living beings (as Paramātmā), and He is controlling all of them in the material world under the agency of His external energy. Therefore it is clearly mentioned that the Lord is the supreme controller and that the living entities are controlled by the Lord.
(Srimad Bhagavatam----2:9:36----purport).

Because the so-called great leaders of human society are ignorant of this great knowledge of bhakti-yoga and are always engaged in ignoble acts of sense gratification, bewildered by the external energy of the Lord, they are stubborn rebels against the supremacy of the Supreme Personality of Godhead, and they never agree to surrender unto Him because they are fools, miscreants and the lowest type of human beings.
(Srimad Bhagavatam----2:9:36----purport).

The Supreme Personality of Godhead, Hari, is the object for fulfilling the senses of all living entities. Illusioned by the glaring reflection of the external energy, the living entities worship the senses instead of engaging them properly in fulfilling the desires of the Supreme.
(Srimad Bhagavatam----2:9:39----purport).

The conditioned souls, being unaware of this very simple fact because of forgetting their relationship with the Lord of Vaikuṇṭha, try to plan out a permanent life in this material world. Being illusioned by the external energy, they thus become engaged in various types of economic and religious development, forgetting that they are meant for going back home, back to Godhead.
(Srimad Bhagavatam----2:10:4----purport).

The illusioned living entity who claims to be the lord of his senses is under the clutches of the external energy of the Lord. As long as a living entity continues to be puffed up by his tiny existence, he is to be understood to be under the stringent control of the external energy of the Lord, and there is no question of liberation from the clutches of illusion (māyā), however much one may declare himself a liberated soul.
(Srimad Bhagavatam----2:10:24----purport).

Because they have been captivated by the external energy of the Supreme Lord, they have completely forgotten the Supreme Lord Viṣṇu, and thus they have taken it for granted that this life, as presently manifested under the conditions of material nature, is all in all for enjoying the highest amount of sense gratification. But such a wrong conception of life cannot give anyone the desired peace of mind, and thus in spite of all advancement in knowledge by use of the resources of nature, no one is happy in this material civilization.
(Srimad Bhagavatam----2:10:25----purport).

A pure devotee of the Lord is never perturbed by an awkward position created by the external energy of the Lord. In Bhagavad-gītā (3.27) it is stated:
prakṛteḥ kriyamāṇāni
guṇaiḥ karmāṇi sarvaśaḥ
ahaṅkāra-vimūḍhātmā
kartāham iti manyate
A conditioned soul is absorbed in material existence under the influence of different modes of external energy. Absorbed in the false ego, he thinks that he is doing everything by himself. The external energy of the Lord, the material nature, is fully under the control of the Supreme Lord, and the conditioned soul is fully under the grip of the external energy. Therefore, the conditioned soul is fully under the control of the law of the Lord. But, due to illusion only, he thinks himself independent in his activities.
(Srimad Bhagavatam----3:1:16----purport).

The whole world is compared to a forest. At any moment there may be a flare-up of fire in the forest due to friction. No one goes to the forest to set it on fire, but due only to friction between bamboos, fire takes place and burns an entire forest. Similarly, in the greater forest of worldly transaction, the fire of war takes place because of the violent passion of the conditioned souls illusioned by the external energy. Such a worldly fire can be extinguished only by the water of the mercy cloud of saints, just as a forest fire can be extinguished only by rains falling from a cloud.
(Srimad Bhagavatam----3:1:21----purport).

It was then arranged for them to be sent back to their abodes so that others could see that the powerful Yadu dynasty was no longer in the world. In the previous verse, the word anujñāta, indicating that the whole sequence of events was arranged by the Lord, is significant. These particular pastimes of the Lord are not a manifestation of His external energy, or material nature. Such an exhibition of His internal potency is eternal, and therefore one should not conclude that the Yadus and Bhojas died in a drunken state in an ordinary fratricidal war. Śrī Jīva Gosvāmī comments on these incidents as magical performances.
(Srimad Bhagavatam----3:4:3----purport).

Great unalloyed devotees of the Lord are compassionate towards the fallen, and therefore they travel all over the world with the mission of bringing souls back to Godhead, back to home. Such pure devotees of the Lord carry the message of Godhead in order to deliver the fallen souls, and therefore the common man who is bewildered by the influence of the external energy of the Lord should avail himself of their association.
(Srimad Bhagavatam----3:5:3----purport).

Lord Kṛṣṇa is the original Personality of Godhead from whom the three creative incarnations, namely the puruṣa-avatāras—Kāraṇārṇavaśāyī Viṣṇu, Garbhodakaśāyī Viṣṇu and Kṣīrodakaśāyī Viṣṇu—expand. The whole material creation is conducted by the three puruṣas in successive stages under the external energy of the Lord, and thus material nature is controlled by Him.
(Srimad Bhagavatam----3:5:5----purport).

Family affection is an illusory manifestation of the external energy, and it is the only impetus for all mundane activities. As long as there is mundane activity and the mind is absorbed in such engagement, one has to undergo the repetition of birth and death in the current material nescience.
(Srimad Bhagavatam----3:5:11----purport).

The Lord is the supreme seer because only by His glance did the material energy become active for cosmic manifestation. At that time the seer was there, but theexternal energy, over which the glance of the Lord is cast, was not present. He felt somewhat insufficient, like a husband feeling lonely in the absence of his wife. This is a poetic simile. The Lord wanted to create the cosmic manifestation to give another chance to the conditioned souls who were dormant in forgetfulness. The cosmic manifestation gives the conditioned souls a chance to go back home, back to Godhead, and that is its main purpose. The Lord is so kind that in the absence of such a manifestation He feels something wanting, and thus the creation takes place. Although the creation of the internal potency was manifested, the other potency appeared to be sleeping, and the Lord wanted to awaken her to activity, just as a husband wants to awaken his wife from the sleeping state for enjoyment. It is the compassion of the Lord for the sleeping energy that He wants to see her awaken for enjoyment like the other wives who are awake. The whole process is to enliven the sleeping conditioned souls to the real life of spiritual consciousness so that they may thus become as perfect as the ever-liberated souls in the Vaikuṇṭhalokas.
(Srimad Bhagavatam----3:5:24----purport).

All material creations take place from subtle to gross. The entire universe has developed in that manner. From the sky developed the touch sensation, which is a mixture of eternal time, theexternal energy and the glance of the Personality of Godhead. The touch sensation developed into the air in the sky. Similarly, all other gross matter also developed from subtle to gross: sound developed into sky, touch developed into air, form developed into fire, taste developed into water, and smell developed into earth.
(Srimad Bhagavatam----3:5:33----purport).

The sky has only one quality, namely sound, but by the interaction of the sky with the glance of the Lord, mixed with eternal time and external nature, the air is produced, which has two qualities—sound and touch. Similarly after the air is created, interaction of sky and air, touched by time and the external energy of the Lord, produces electricity. And after the interaction of electricity with air and sky, mixed with time, external energy and the Lord's glance over them, the water is produced. In the final stage of sky there is one quality, namely sound; in the air two qualities, sound and touch; in the electricity three qualities, namely sound, touch and form; in the water four qualities, sound, touch, form and taste; and in the last stage of physical development the result is earth, which has all five qualities—sound, touch, form, taste and smell.
(Srimad Bhagavatam----3:5:36----purport).

The demigods are expanded parts and parcels of the Supreme Lord Viṣṇu, and they are embodied by time, external energy and partial consciousness of the Supreme. Human beings, animals, birds, etc., are also parts and parcels of the Lord and have different material bodies, but they are not the controlling deities of material affairs. They are, rather, controlled by such demigods.
(Srimad Bhagavatam----3:5:38----purport).

The conditioned soul in the material world wants to lord it over others. Illusioned by the external energy of the Lord, he is forced to become a servant of the material world. That is the real position of the conditioned soul. The last snare of the illusory, external energy is the conception of becoming one with the Lord, and due to this conception the illusioned soul remains in the bondage of material energy, falsely thinking himself a liberated soul and "as good as Nārāyaṇa."
(Srimad Bhagavatam----3:6:33----purport).

Since Arjuna was unable to estimate the length and breadth of the potency of the Lord, who else would be able to do so? One may only indulge in miscalculation like the frog-philosopher. The frog-philosopher wanted to estimate the length and breadth of the Pacific Ocean by his experience of a well three cubic feet large, and thus he began to puff himself up to become as big as the Pacific Ocean, but at last he burst and died by this process. This story is applicable to the mental philosophers who, under the illusion of the Lord'sexternal energy, indulge in estimating the length and breadth of the Supreme Lord. The best path is to become a cool-headed, submissive devotee of the Lord, try to hear about the Lord from the bona fide spiritual master, and thus serve the Lord in transcendental loving service.
(Srimad Bhagavatam----3:6:35----purport).

The Personality of Godhead has unlimited potencies to create and manifest many wonderful things, both temporary and permanent. Because this material world is the creation of His external energy, it thus appears to be temporary; it is manifested at certain intervals, maintained for some time, and again dissolved and conserved in His own energy.
(Srimad Bhagavatam----3:7:2----purport).
