There is no difference between the Lord's Self and the Lord's transcendental body. The expansions execute differential activities. When the Lord, however, appears in His person as Lord Śrī Kṛṣṇa, His other plenary portions also join in Him by His inconceivable potency called yogamāyā, and thus the Lord Kṛṣṇa of Vṛndāvana is different from the Lord Kṛṣṇa of Mathurā or the Lord Kṛṣṇa of Dvārakā. The virāṭ-rūpa of Lord Kṛṣṇa is also different from Him, by His inconceivable potency. The virāṭ-rūpa exhibited on the Battlefield of Kurukṣetra is the material conception of His form. Therefore it should be understood that when Lord Kṛṣṇa was apparently killed by the bow and arrow of the hunter, the Lord left His so-called material body in the material world.
(Srimad Bhagavatam----1:14:8----purport).

Such mahā-bhāgavatas, or first-grade devotees, although moving amongst men, are not contaminated by honor or insult, hunger or satisfaction, sleep or wakefulness, which are all resultant actions of the three modes of material nature. Similarly, some of them are engaged in worldly dealings, yet are unaffected. Unless these neutralities of life are there, one cannot be considered situated in transcendence. The Divinity and His associates are on the same transcendental plane, and their glories are always sanctified by the action of yogamāyā, or the internal potency of the Lord. The devotees of the Lord are always transcendental, even if they are sometimes found to have fallen in their behavior.
(Srimad Bhagavatam----1:11:38----purport).

Even the transcendental wives of Lord Śrī Kṛṣṇa did not know completely the unfathomable glories of the Lord. This ignorance is not mundane because there is some action of the internal potency of the Lord in the exchange of feelings between Him and His eternal associates. The Lord exchanges transcendental relations in five ways, as proprietor, master, friend, son and lover, and in each of these pastimes He plays fully by the potency of yogamāyā, the internal potency.
(Srimad Bhagavatam----1:11:39----purport).

The Lord is not approachable by everyone because He is curtained by His yogamāyā potency. But one should not wrongly conclude that the Lord was formerly unmanifested and has now manifested Himself in the human form. This misconception of the formlessness of the Supreme Personality of Godhead is due to the yogamāyā curtain of the Lord and can be removed only by the Supreme Will, as soon as the conditioned soul surrenders unto Him.
(Srimad Bhagavatam----2:5:20----purport).

This ignorance of the personal feature of the Lord is due simply to ignorance of the mixture of different modes. The impersonalist thus cannot conceive of the Lord's eternal spiritual form of eternal knowledge, bliss and existence. The reason is that the Lord reserves the right of not exposing Himself to the nondevotee who, even after a thorough study of literature like the Bhagavad-gītā, remains an impersonalist simply by obstinacy. This obstinacy is due to the action of yogamāyā, a personal energy of the Lord that acts like an aide-de-camp by covering the vision of the obstinate impersonalist.
(Srimad Bhagavatam----2:5:24----purport).

The Lord is called anupalakṣya-mārgaḥ or, in still more technical Vedic terms, avāṅ-manasā gocaraḥ: one who is never to be seen or realized by the limited sense perception of the people in general. In the Bhagavad-gītā (7.25) it is said by the Lord, nāhaṁ prakāśaḥ sarvasya yogamāyā-samāvṛtaḥ. In other words, He reserves the right of not being exposed to anyone and everyone. Only the bona fide devotees can know Him by His specific symptoms, and out of many, many such symptoms, one symptom is mentioned here in this verse, that the Lord is sita-kṛṣṇa-keśaḥ, or one who is observed always with beautiful black hair.
(Srimad Bhagavatam----2:7:26----purport).

One day Lord Kṛṣṇa as the naughty child disturbed His mother Yaśodā, and she began to tie up the child with ropes just to punish Him. But no matter how much rope she used, she found it always insufficient. Thus she became fatigued, but in the meantime the Lord opened His mouth, and the affectionate mother saw within the mouth of her son all the universes situated together. The mother was astonished, but out of her deep affection for Kṛṣṇa she thought that the Almighty Godhead Nārāyaṇa had kindly looked after her son just to protect Him from all the continuous calamities happening to Him. Because of her deep affection for Kṛṣṇa, she could never think that her very son was Nārāyaṇa, the Personality of Godhead Himself. That is the action of yogamāyā, the internal potency of the Supreme Lord, which acts to perfect all the pastimes of the Lord with His different types of devotees. Who could play such wonders without being God?
(Srimad Bhagavatam----2:7:30----purport).

The Lord is knowable only by one who is a surrendered soul. Herein Brahmājī, the greatest of all material living beings, acknowledges this truth. Therefore, the fruitless spoiling of energy by pursuing the path of experimental knowledge must be given up. One should gain knowledge by surrendering unto the Lord and by acknowledging the authority of the persons mentioned herein. The Lord is unlimited and, by the grace of the yogamāyā, helps the surrendered soul to know Him proportionately with the advance of one's surrender.
(Srimad Bhagavatam----2:7:43-45----purport).

The omnipotent Lord, by His different energies, can perform anything and everything He likes. The creation of the cosmic world is done by His yogamāyā energy.
(Srimad Bhagavatam----3:5:22----purport).

The froggish philosophers may go on with their mental speculations on the subject matter of the virāṭ, the gigantic form exhibited by the yogamāyā internal potency of the Supreme Personality of Godhead, but factually no one can measure such a vast exhibition.
(Srimad Bhagavatam----3:6:35----purport).

The energy of the Lord called avidyā is the bewildering factor of the conditioned souls. The material nature is called avidyā, or ignorance, but to the devotees of the Lord engaged in pure devotional service, this energy becomes vidyā, or pure knowledge. This is confirmed in Bhagavad-gītā. The energy of the Lord transforms from mahāmāyā toyogamāyā and appears to pure devotees in her real feature.
(Srimad Bhagavatam----3:10:17----purport).

For the impersonalists and the so-called yogīs, the Lord is always hidden by the curtain of yogamāyā. Bhagavad-gītā says that even when Lord Kṛṣṇa was seen by everyone while He was present on the surface of the earth, the impersonalists and the so-called yogīs could not see Him because they were devoid of devotional eyesight.
(Srimad Bhagavatam----3:15:50----purport).

The sages were almost too puzzled to speak before the Supreme Personality of Godhead for the first time, and the hairs of their bodies stood erect due to their extreme joy. The highest opulence in the material world is called pārameṣṭhya, the opulence of Brahmā. But that material opulence of Brahmā, who lives on the topmost planet within this material world, cannot compare to the opulence of the Supreme Lord because the transcendental opulence in the spiritual world is caused by yogamāyā, whereas the opulence in the material world is caused by mahāmāyā.
(Srimad Bhagavatam----3:16:15----purport).

The Lord kills the process of birth and death and keeps Himself invisible. The activities of the Lord's internal potency are inconceivable, but by a slight exhibition of this potency, the Lord, by His grace, can deliver one from nescience. Śucaḥ means "miseries"; the miseries of material existence can be extinguished by the Lord by His potential energy of internal yogamāyā.
(Srimad Bhagavatam----3:18:4----purport).

As stated in Bhagavad-gītā, those who are great souls, mahātmās, are not under the control of the material energy. The Supreme Lord has two energies, material and spiritual. The living entities are marginal energy. As marginal energy, a person may be under the control of the material energy or the spiritual energy (yogamāyā). Kardama Muni was a great soul, and therefore he was under the spiritual energy, which means that he was directly connected with the Supreme Lord. The symptom of this is Kṛṣṇa consciousness, constant engagement in devotional service.
(Srimad Bhagavatam----3:23:10----purport).

In this verse the word māyayā means "by your causeless mercy." The Māyāvādī philosophers explain the word māyā as meaning "illusion" or "falseness." However, there is another meaning of māyā—that is, "causeless mercy." There are two kinds of māyā-yogamāyā and mahāmāyā. Mahāmāyā is an expansion of yogamāyā, and both these māyās are different expressions of the Lord's internal potencies.
(Srimad Bhagavatam----4:16:2----purport).

One who is unintelligent, who has no eyes to see the future, simply creates enmity and fights with others for sense gratification. As a result, one suffers in the next life, but due to being like a blind man, he continues to act in such a way that he suffers unlimitedly. Such a person is a mūḍha, one who simply wastes his time and does not understand the Lord's devotional service. As stated in Bhagavad-gītā (7.25):
nāhaṁ prakāśaḥ sarvasya
yogamāyā-samāvṛtaḥ
mūḍho 'yaṁ nābhijānāti
loko mām ajam avyayam
"I am never manifest to the foolish and unintelligent. For them I am covered by My eternal creative potency (yogamāyā); and so the deluded world knows Me not, who am unborn and infallible."
(Srimad Bhagavatam----5:5:16----purport).

Generally yogīs desire the yogic perfections of aṇimā, laghimā, mahimā, prākāmya, prāpti, īśitva, vaśitva and kāmāvasāyitā. Lord Ṛṣabhadeva, however, never aspired for all these material things. Such siddhis (perfections) are presented by the illusory energy of the Lord. The real purpose of the yoga system is to achieve the favor and shelter of the lotus feet of the Supreme Personality of Godhead, but this purpose is covered by the illusory energy of yogamāyā. So-called yogīs are therefore allured by the superficial material perfections of aṇimā, laghimā, prāpti and so forth. Consequently ordinary yogīs cannot compare to Lord Ṛṣabhadeva, the Supreme Personality of Godhead.
(Srimad Bhagavatam----5:6:15----purport).

In Bhagavad-gītā (4.6) Lord Kṛṣṇa says, sambhavāmy ātma-māyayā: "I appear by My internal potency. "The word ātma-māyā refers to the Lord's personal potency,yogamāyā. After creating both the material world and spiritual world through yogamāyā, the Supreme Personality of Godhead personally maintains them by expanding Himself in different categories as the Viṣṇu mūrtis and the demigods. He maintains the material creation from beginning to end, and He personally maintains the spiritual world.
(Srimad Bhagavatam----5:20:41----purport).

The Lord comes to this material world through the agency of His internal potency, and similarly, when a devotee or associate of the Lord descends to this material world, he does so through the action of the spiritual energy. Any pastime conducted by the Supreme Personality of Godhead is an arrangement by yogamāyā, not mahāmāyā. Therefore it is to be understood that when Jaya and Vijaya descended to this material world, they came because there was something to be done for the Supreme Personality of Godhead. Otherwise it is a fact that no one falls from Vaikuṇṭha.
(Srimad Bhagavatam----7:1:35----purport).
