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.
(Sri Ishopanishad).

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.
(Sri Ishopanishad).

The system of hearing from undisturbed authorities is approved in this mantra. Unless one hears from a bona fide ācārya, who is never disturbed by the changes of the material world, one cannot have the real key to transcendental knowledge. The bona fide spiritual master, who has also heard the śruti-mantras, or Vedic knowledge, from his undisturbed ācārya, never presents anything that is not mentioned in the Vedic literature. In the Bhagavad-gītā (9.25) it is clearly said that those who worship the pitṛs, or forefathers, attain the planets of the forefathers, that the gross materialists who make plans to remain here stay in this world, and that the devotees of the Lord who worship none but Lord Kṛṣṇa, the supreme cause of all causes, reach Him in His spiritual sky. Here also in Śrī Īśopaniṣad it is verified that one achieves different results by different modes of worship.
(Sri Ishopanishad).

With a single fragment of Myself I pervade and support this entire universe." Thus by His one plenary expansion, the all-pervading Paramātmā, the Lord maintains the complete material cosmic creation. He also maintains all manifestations in the spiritual world. Therefore in this śruti-mantra of Śrī Īśopaniṣad, the Lord is addressed as pūṣan, the ultimate maintainer.
The Personality of Godhead, Śrī Kṛṣṇa, is always filled with transcendental bliss (ānanda-mayo 'bhyāsāt). When He was present at Vṛndāvana in India five thousand years ago, He always remained in transcendental bliss, even from the beginning of His childhood pastimes. The killings of various demons—such as Agha, Baka, Pūtanā and Pralamba—were but pleasure excursions for Him. In His village of Vṛndāvana He enjoyed Himself with His mother, brother and friends, and when He played the role of a naughty butter thief, all His associates enjoyed celestial bliss by His stealing.
(Sri Ishopanishad).

All of these planets are situated in a corner of the brahma-jyotir. This brahma-jyotir is but the personal rays of the Supreme Personality of Godhead, Govinda, whom I worship." This mantra from the Brahma-saṁhitā is spoken from the platform of factual realization of the Absolute Truth, and the śruti-mantra of Śrī Īśopaniṣad under discussion confirms this mantra as a process of realization. The Īśopaniṣad mantra is a simple prayer to the Lord to remove the brahma-jyotir so that one can see His real face.
(Sri Ishopanishad).

Any action or reaction of a part of a body becomes a cognizable fact to the embodied soul. Similarly, since the creation is the body of the Absolute Truth, then everything in the creation is known to the Absolute, both directly and indirectly.
In the śruti-mantra it is stated that the absolute whole, or Brahman, is the ultimate source of everything. Everything emanates from Him, everything is maintained by Him, and at the end everything enters into Him again. That is the law of nature. This is confirmed in the smṛti-mantra. There it is said that at the beginning of Brahmā’s millennium the source from which everything emanates is the Absolute Truth, or Brahman, and that at the end of that millennium the reservoir into which everything enters is that same Absolute Truth. Material scientists haphazardly take it for granted that the ultimate source of this planetary system is the sun, but they are unable to explain the source of the sun.
(Teachings of Lord Caitanya).

Whenever the authority of the Lord is neglected, the penalties dealt by the laws of nature are always there.
That the Supreme Lord, the Personality of Godhead, is all-perfect is confirmed in all śruti-mantras. It is said in the śruti-mantras that the all-perfect Lord glanced over matter and thus created all living beings. The living beings are parts and parcels of the Lord, and He impregnates the vast material nature with the seeds of the spiritual sparks. Thus the creative energies are set in motion for so many wonderful creations. When one atheist argued that God is no more expert than the manufacturer of a subtle watch that has so many delicate parts, we had to reply that God is a greater mechanic than the watchmaker because He creates one machine in male and female forms that go on producing innumerable similar machines without the further attention of God.
(Teachings of Lord Caitanya).

Because no one can be equal to God in intelligence, another name for God is asamaurdhva, which indicates that no one is equal to or greater than Him. Everyone has his intellectual equal and superior, and no one can claim that he has neither. But this is not the case with the Lord. The śruti-mantras indicate that before the creation of the material universe there existed the Lord, who is the master of everyone. It was the Lord who instructed Brahmā in Vedic knowledge. That Personality of Godhead has to be obeyed in all respects. Anyone who wants to become freed from material entanglement must surrender unto Him, and this is confirmed in the Bhagavad-gītā.
Unless one surrenders unto the lotus feet of the Personality of Godhead, it is sure and certain that one will be bewildered, even if he happens to be a great mind. Only when great minds surrender unto the lotus feet of Vāsudeva and know fully that Vāsudeva is the cause of all causes, as confirmed in the Bhagavad-gītā (7.19).
