Here is a description of the transcendental and eternal form of the Absolute Personality of Godhead. The Supreme Lord is not formless. He has His own transcendental form, which is not at all similar to the forms of the mundane world. The forms of the living entities in this world are embodied in material nature, and they work like any material machine. The anatomy of a material body must have a mechanical construction with veins and so forth, but the transcendental body of the Supreme Lord has nothing like veins. It is clearly stated here that He is unembodied, which means that there is no difference between His body and His soul. Nor is He forced to accept a body according to the laws of nature, as we are. In materially conditioned life, the soul is different from the gross embodiment and subtle mind. For the Supreme Lord, however, there is never any such difference between Him and His body and mind. He is the Complete Whole, and His mind, body and He Himself are all one and the same.

In the Brahma-saṁhitā (5.1) there is a similar description of the Supreme Lord. He is described there as sac-cid-ānanda-vigraha, which means that He is the eternal form fully representing transcendental existence, knowledge and bliss. As such, He does not require a separate body or mind, as we do in material existence. The Vedic literature clearly states that the Lord’s transcendental body is completely different from ours; thus He is sometimes described as formless. This means that He has no form like ours and that He is devoid of a form we can conceive of. In the Brahma-saṁhitā (5.32) it is further stated that with each and every part of His body He can do the work of the other senses. This means that the Lord can walk with His hands, accept things with His legs, see with His hands and feet, eat with His eyes, etc. In the śruti-mantras it is also said that although the Lord has no hands and legs like ours, He has a different type of hands and legs, by which He can accept all that we offer Him and run faster than anyone. These points are confirmed in this eighth mantra through the use of words like śukram (“omnipotent”).

The Lord’s worshipable form (arcā-vigraha), which is installed in temples by authorized ācāryas who have realized the Lord in terms of Mantra Seven, is nondifferent from the original form of the Lord. The Lord’s original form is that of Śrī Kṛṣṇa, and Śrī Kṛṣṇa expands Himself into an unlimited number of forms, such as Baladeva, Rāma, Nṛsiṁha and Varāha. All of these forms are one and the same Personality of Godhead. Similarly, the arcā-vigraha worshiped in temples is also an expanded form of the Lord. By worshiping the arcā-vigraha, one can at once approach the Lord, who accepts the service of a devotee by His omnipotent energy. The arcā-vigraha of the Lord descends at the request of the ācāryas, the holy teachers, and works exactly in the original way of the Lord by virtue of the Lord’s omnipotence. Foolish people who have no knowledge of Śrī Īśopaniṣad or any of the other śruti-mantras consider the arcā-vigraha, which is worshiped by pure devotees, to be made of material elements. This form may be seen as material by the imperfect eyes of foolish people or kaniṣṭha-adhikārīs, but such people do not know that the Lord, being omnipotent and omniscient, can transform matter into spirit and spirit into matter, as He desires.

In the Bhagavad-gītā (9.11–12) the Lord regrets the fallen condition of men with little knowledge who deride Him because He descends like a man into this world. Such poorly informed persons do not know the omnipotence of the Lord. Thus the Lord does not manifest Himself in full to the mental speculators. He can be appreciated only in proportion to one’s surrender to Him. The fallen condition of the living entities is due entirely to forgetfulness of their relationship with God.

In this mantra, as well as in many other Vedic mantras, it is clearly stated that the Lord has been supplying goods to the living entities from time immemorial. A living being desires something, and the Lord supplies the object of that desire in proportion to one’s qualification. If a man wants to be a high-court judge, he must acquire not only the necessary qualifications but also the consent of the authority who can award the title of high-court judge. The qualifications in themselves are insufficient for one to occupy the post: it must be awarded by some superior authority. Similarly, the Lord awards enjoyment to living entities in proportion to their qualifications, but good qualifications in themselves are not sufficient to enable one to receive awards. The mercy of the Lord is also required.

Ordinarily the living being does not know what to ask from the Lord, nor which post to seek. When the living being comes to know his constitutional position, however, he asks to be accepted into the transcendental association of the Lord in order to render transcendental loving service unto Him. Unfortunately, living beings under the influence of material nature ask for many other things, and they are described in the Bhagavad-gītā (2.41) as having divided, or splayed, intelligence. Spiritual intelligence is one, but mundane intelligence is diverse. In Śrīmad-Bhāgavatam (7.5.30–31) it is stated that those who are captivated by the temporary beauties of the external energy forget the real aim of life, which is to go back to Godhead. Forgetting this, one tries to adjust things by various plans and programs, but this is like chewing what has already been chewed. Nonetheless, the Lord is so kind that He allows the forgetful living entity to continue in this way without interference. Thus this mantra of Śrī Īśopaniṣad uses the very appropriate word yāthātathyataḥ, indicating that the Lord rewards the living entities just in pursuance of their desires. If a living being wants to go to hell, the Lord allows him to do so without interference, and if he wants to go back home, back to Godhead, the Lord helps him.

God is described here as paribhūḥ, the greatest of all. No one is greater than or equal to Him. Other living beings are described here as beggars who ask goods from the Lord. The Lord supplies the things the living entities desire. If the entities were equal to the Lord in potency – if they were omnipotent and omniscient – there would be no question of their begging from the Lord, even for so-called liberation. Real liberation means going back to Godhead. Liberation as conceived of by an impersonalist is a myth, and begging for sense gratification has to continue eternally unless the beggar comes to his spiritual senses and realizes his constitutional position.

Only the Supreme Lord is self-sufficient. When Lord Kṛṣṇa appeared on earth five thousand years ago, He displayed His full manifestation as the Personality of Godhead through His various activities. In His childhood He killed many powerful demons, such as Aghāsura, Bakāsura and Śakaṭāsura, and there was no question of His having acquired such power through any extraneous endeavor. He lifted Govardhana Hill without ever practicing weight-lifting. He danced with the gopīs without social restriction and without reproach. Although the gopīs approached Him with a paramour’s feelings of love, the relationship between the gopīs and Lord Kṛṣṇa was worshiped even by Lord Caitanya, who was a strict sannyāsīand rigid follower of disciplinary regulations. To confirm that the Lord is always pure and uncontaminated, Śrī Īśopaniṣaddescribes Him as śuddham (antiseptic) and apāpa-viddham (prophylactic). He is antiseptic in the sense that even an impure thing can become purified just by touching Him. The word “prophylactic” refers to the power of His association. As mentioned in the Bhagavad-gītā (9.30–31), a devotee may appear to be su-durācāra, not well behaved, in the beginning, but he should be accepted as pure because he is on the right path. This is due to the prophylactic nature of the Lord’s association. The Lord is also apāpa-viddham because sin cannot touch Him. Even if He acts in a way that appears to be sinful, such actions are all-good, for there is no question of His being affected by sin. Because in all circumstances He is śuddham, most purified, He is often compared to the sun. The sun extracts moisture from many untouchable places on the earth, yet it remains pure. In fact, it purifies obnoxious things by virtue of its sterilizing powers. If the sun, which is a material object, is so powerful, then we can hardly begin to imagine the purifying strength of the all-powerful Lord.
