Sri Isopanisad

Perfect knowledge means knowing Kṛṣṇa as the root of this Brahman effulgence. This knowledge can be gained from such scriptures as Śrīmad-Bhāgavatam, which perfectly elaborates the science of Kṛṣṇa. In Śrīmad-Bhāgavatam, the author, Śrīla Vyāsadeva, has established that one will describe the Supreme Truth as Brahman, Paramātmā or Bhagavān according to one's realization of Him.

Sri Isopanisad 15, Purport:

The Paramātmā feature of the Personality of Godhead is one of three plenary expansions, or viṣṇu-tattvas, collectively known as the puruṣa-avatāras. One of these viṣṇu-tattvas who is within the universe is known as Kṣīrodakaśāyī Viṣṇu. He is the Viṣṇu among the three principal deities—Brahmā, Viṣṇu and Śiva—and He is the all-pervading Paramātmā in each and every individual living entity. The second viṣṇu-tattva within the universe is Garbhodakaśāyī Viṣṇu, the collective Supersoul of all living entities. Beyond these two is Kāraṇodakaśāyī Viṣṇu, who lies in the Causal Ocean. He is the creator of all universes. The yoga system teaches the serious student to meet the viṣṇu-tattvas after going beyond the twenty-four material elements of the cosmic creation. The culture of empiric philosophy helps one realize the impersonal brahma-jyotir, which is the glaring effulgence of the transcendental body of Lord Śrī Kṛṣṇa. That the brahma-jyotir is Kṛṣṇa's effulgence is confirmed in the Bhagavad-gītā (14.27) as well as the Brahma-saṁhitā (5.40):

yasya prabhā-prabhavato jagad-aṇḍa-koṭi-

koṭiṣv aśeṣa-vasudhādi vibhūti-bhinnam

tad brahma niṣkalam anantam aśeṣa-bhūtaṁ

govindam ādi-puruṣaṁ tam ahaṁ bhajāmi

"In the millions and millions of universes there are innumerable planets, and each and every one of them is different from the others by its cosmic constitution. 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. This brahma-jyotir effulgence is described in detail in several mantras of the Muṇḍaka Upaniṣad (2.2.10-12):

hiraṇmaye pare kośe

virajaṁ brahma niṣkalam

tac chubhraṁ jyotiṣāṁ jyotis

tad yad ātma-vido viduḥ

na tatra sūryo bhāti na candra-tārakaṁ

nemā vidyuto bhānti kuto 'yam agniḥ

tam eva bhāntam anu bhāti sarvaṁ

tasya bhāsā sarvam idaṁ vibhāti

brahmaivedam amṛtaṁ purastād brahma

paścād brahma dakṣiṇataś cottareṇa

adhaś cordhvaṁ ca prasṛtaṁ brahmai-

vedaṁ viśvam idaṁ variṣṭham

"In the spiritual realm, beyond the material covering, is the unlimited Brahman effulgence, which is free from material contamination. That effulgent white light is understood by transcendentalists to be the light of all lights. In that realm there is no need of sunshine, moonshine, fire or electricity for illumination. Indeed, whatever illumination appears in the material world is only a reflection of that supreme illumination. That Brahman is in front and in back, in the north, south, east and west, and also overhead and below. In other words, that supreme Brahman effulgence spreads throughout both the material and spiritual skies."

Perfect knowledge means knowing Kṛṣṇa as the root of this Brahman effulgence. This knowledge can be gained from such scriptures as Śrīmad-Bhāgavatam, which perfectly elaborates the science of Kṛṣṇa. In Śrīmad-Bhāgavatam, the author, Śrīla Vyāsadeva, has established that one will describe the Supreme Truth as Brahman, Paramātmā or Bhagavān according to one's realization of Him. Śrīla Vyāsadeva never states that the Supreme Truth is a jīva, an ordinary living entity. The living entity should never be considered the all-powerful Supreme Truth. If he were the Supreme, he would not need to pray to the Lord to remove His dazzling cover so that the living entity could see His real face.

The conclusion is that one who has no knowledge of the potencies of the Supreme Truth will realize the impersonal Brahman. Similarly, when one realizes the material potencies of the Lord but has little or no information of the spiritual potencies, he attains Paramātmā realization. Thus both Brahman and Paramātmā realization of the Absolute Truth are partial realizations. However, when one realizes the Supreme Personality of Godhead, Śrī Kṛṣṇa, in full potency after the removal of the hiraṇmaya-pātra, one realizes vāsudevaḥ sarvam iti: (BG 7.19) Lord Śrī Kṛṣṇa, who is known as Vāsudeva, is everything—Brahman, Paramātmā and Bhagavān. He is Bhagavān, the root, and Brahman and Paramātmā are His branches.

In the Bhagavad-gītā (6.46-47) there is a comparative analysis of the three types of transcendentalists—the worshipers of the impersonal Brahman (jñānīs), the worshipers of the Paramātmā feature (yogīs) and the devotees of Lord Śrī Kṛṣṇa (bhaktas). It is stated there that the jñānīs, those who have cultivated Vedic knowledge, are better than ordinary fruitive workers, that the yogīs are still greater than the jñānīs, and that among all yogīs, those who constantly serve the Lord with all their energies are the topmost. In summary, a philosopher is better than a laboring man, a mystic is superior to a philosopher, and of all the mystic yogīs, he who follows bhakti-yoga, constantly engaging in the service of the Lord, is the highest. Śrī Īśopaniṣad directs us toward this perfection.
