God is beyond Mind and Intellect

The infinite Universe of universes and worlds is before our eyes. But there is present behind it an indescribable power which is running the entire "show". Even those who do not admit the reality of religion and say that man cannot know God's nature and form, do not deny the existence of this Supreme Power. The well-known philosopher, Herbert Spencer, came to the conclusion that Reality is neither known nor can it be known by anyone. He wanted to discover the Reality through intellect and reasoning. But Reality is beyond the reach of the mind and the senses. His conclusion, therefore, that the Reality is not conceivable by the mind and the senses, was inevitable. Every phenomenon of the world can be explained by reason, but in so far as access to spiritual regions is concerned, reason is useless. Spencer had, however, to admit the existence of Reality and in the January, 1884 issue of the monthly magazine "Nineteenth Century", he wrote as follows about the ultimate cause of this Universe.

There is an eternal and immortal power and everything has manifested from the same.

The German philosopher Kant became impatient and gave up even thinking about the Unknowable Reality. John Stuart Mill, in "Three Essays on Religion", says that whatever experience tells us about the First Cause and what we understand by the word 'Cause' is that the primal and immanent essence that pervades all causes is nothing but force. These learned men are of the view that this universe originated from an Indescribable Force and that that Force is eternal and immortal. In the Brihadarnayak Upanishad, Rishis say that "Reality is beyond the reach of any possible description in terms of form and matter, nor can it be described in these terms. 

Just as it is impossible to extract oil from sand or to quench thirst with wine, similarly it is useless even to conceive that Brahm (the Lord) can be known through learning". 

In this Upanishad there is a short aphorism "Ned Neti" (Not this, not this). It is repeated four times. Its meaning is that what is described is not Brahm or the Lord. Or in other words, what is beyond name and form is Brahm. As He is without qualities and indescribable, He is not a subject for these eyes, nor can mind and speech have access to Him.

Guru Nanak also says that He is beyond the realm of thought:

He cannot be conceived however hard one may think.
