aparimita dhruvas tanu-bhrto yadi sarva-gatas
tarhi na sasyateti niyamo dhruva netaratha
ajani ca yan-mayam tad avimucya niyantr bhavet
samam anujanatam yad amatam mata-dustataya
Translation:
If the countless living entities were all-pervading and possessed forms that never changed, You could not possibly be their absolute ruler, O immutable one. But since they are Your localized expansions and their forms are subject to change, You do control them. Indeed, that which supplies the ingredients for the generation of something is necessarily its controller because a product never exists apart from its ingredient cause. It is simply illusion for someone to think that he knows the Supreme Lord, who is equally present in each of His expansions, since whatever knowledge one gains by material means must be imperfect.
Purport:
Because the conditioned soul cannot directly understand the Supreme, the Vedas commonly refer to that Supreme Truth in such impersonal terms as Brahman and om tat sat. If an ordinary scholar presumes to know the confidential meaning of these symbolic references, he should be rejected as an imposter. In the words of Sri Kena Upanisad (2.1), yadi manyase su-vedeti dabhram evapi nunam tvam vettha brahmano rupam, yad asya tvam yad asya devesu: “If you think you know Brahman well, then your knowledge is very meager. If you think you can identify Brahman’s form from among the demigods, indeed you know but little.” And again:
yasyamatam tasya matam
matam yasya na veda sah
avijñatam vijanatam
vijñatam avijanatam
“Whoever denies having any opinion of his own about the Supreme Truth is correct in his opinion, whereas one who has his own opinion about the Supreme does not know Him. He is unknown to those who claim to know Him, and can only be known by those who do not claim to know Him.” (Kena Upanisad 2.3)
Acarya Sridhara Svami gives the following explanation of this verse: Many philosophers have studied the mysteries of life from various perspectives and have formed widely differing theories. The Advaita Mayavadis, for example, propose that there is only one living being and one power of illusion (avidya) that covers him, producing the appearance of plurality. But this hypothesis leads to the absurd conclusion that when any one living being becomes liberated, everyone obtains liberation. If, on the other hand, there are many avidyas to cover the one living being, each avidya will cover only some part of him, and we would have to talk about his becoming partly liberated at particular times while his other parts remain in bondage. This is also obviously absurd. Thus the plurality of living beings is an unavoidable conclusion.
Furthermore, there are other theoreticians, namely the proponents of Nyaya and Vaisesika, who claim that the jiva soul is infinite in size. If souls were infinitesimal, these scholars argue, they would not pervade their own bodies, whereas if they were of medium size they would be divisible into parts and thus could not be eternal, at least according to the axioms of Nyaya-Vaisesika metaphysics. But if the numerous eternal jiva souls are each infinitely large, how could they be covered by any power of bondage, whether belonging to avidya or to the Supreme Lord Himself? According to this theory, there can be no illusion for the soul, no limitations from which to be liberated. The infinite souls must eternally remain as they are, without change. This would mean that the souls would all be equal to God, since He would have no scope for controlling these all-pervading, unchanging rivals.
The Vedic sruti-mantras, which affirm unequivocally the mastery of the Lord over the individual souls, cannot be validly contradicted. A true philosopher must accept the statements of sruti as reliable authority on all matters they touch. Certainly in numerous places the Vedic literatures contrast the Supreme Lord’s perpetual, unchanging oneness with the ever-changing embodiments of living beings caught up in the cycle of birth and death.
Srila Sridhara Svami prays:
antar-yanta sarva-lokasya gitah
srutya yuktya caivam evavaseyah
yah sarva-jñah sarva-saktir nrsimhah
srimantam tam cetasaivavalambe
“In my heart I take shelter of Him who is glorified as the inner controller of all the worlds, and whom the Vedas ascertain in truth through logical reasoning. He is Nrsimha, the omniscient and omnipotent Lord of the goddess of fortune.”
