BG 7.25

7.25 न not? अहम् I? प्रकाशः manifest? सर्वस्य of all? योगमायासमावृतः veiled by YogaMaya? मूढः deluded? अयम् this? न not? अभिजानाति knows? लोकः world? माम् Me? अजम् unborn? अव्ययम् imperishable.Commentary I am not manifest to all the people? but I am certainly manifest to the chosen few who are My devotees? who have taken sole refuge in Me alone. I am not visible to those who are deluded by the three Gunas and the pairs of opposites? and who are screened off by this universe which is a manifestation of the alities of Nature? My YogaMaya or My creative illusion. This veils the understanding of the worldlyminded people. So they are not able to behold the Lord Who keeps Maya under His perfect control.YogaMaya is the union of the three alities of Nature. The illusion or veil spread thery is called YogaMaya. The worldly people are deluded by the illusion born of the union of the three alities. Therefore? they are not able to know the Lord Who is unborn and immutable.This YogaMaya is under the perfect control of the Lord. Isvara is the wielder of Maya. Therefore it cannot obscure His own knowledge? just as the illusion created by the juggler cannot obstruct his,own knowledge or deceive him. The illusion which binds the worldly people cannot in the least affect the Lord Who has kep Maya under his perfect subjugation. (Cf.VII.13IX.5X.7XI.8)

It may be argued that since Kṛṣṇa was visible to everyone when He was present on this earth, how can it be said that He is not manifest to everyone? But actually He was not manifest to everyone. When Kṛṣṇa was present there were only a few people who could understand Him to be the Supreme Personality of Godhead. In the assembly of Kurus, when Śiśupāla spoke against Kṛṣṇa’s being elected president of the assembly, Bhīṣma supported Him and proclaimed Him to be the Supreme God. Similarly, the Pāṇḍavas and a few others knew that He was the Supreme, but not everyone. He was not revealed to the nondevotees and the common man. Therefore in the Bhagavad-gītā Kṛṣṇa says that but for His pure devotees, all men consider Him to be like themselves. He was manifest only to His devotees as the reservoir of all pleasure. But to others, to unintelligent nondevotees, He was covered by His internal potency. In the prayers of Kuntī in the Śrīmad-Bhāgavatam (1.8.19) it is said that the Lord is covered by the curtain of yoga-māyā and thus ordinary people cannot understand Him. This yoga-māyā curtain is also confirmed in the Īśopaniṣad (Mantra 15), in which the devotee prays: hiraṇmayena pātreṇa satyasyāpihitaṁ mukham tat tvaṁ pūṣann apāvṛṇu satya-dharmāya dṛṣṭaye “O my Lord, You are the maintainer of the entire universe, and devotional service to You is the highest religious principle. Therefore, I pray that You will also maintain me. Your transcendental form is covered by the yoga-māyā. The brahma-jyotir is the covering of the internal potency. May You kindly remove this glowing effulgence that impedes my seeing Your sac-cid-ānanda-vigraha, Your eternal form of bliss and knowledge.” The Supreme Personality of Godhead in His transcendental form of bliss and knowledge is covered by the internal potency of the brahma-jyotir, and the less intelligent impersonalists cannot see the Supreme on this account. Also in the Śrīmad-Bhāgavatam (10.14.7) there is this prayer by Brahmā: “O Supreme Personality of Godhead, O Supersoul, O master of all mystery, who can calculate Your potency and pastimes in this world? You are always expanding Your internal potency, and therefore no one can understand You. Learned scientists and learned scholars can examine the atomic constitution of the material world or even the planets, but still they are unable to calculate Your energy and potency, although You are present before them.” The Supreme Personality of Godhead, Lord Kṛṣṇa, is not only unborn but also avyaya, inexhaustible. His eternal form is bliss and knowledge, and His energies are all inexhaustible.
