To realize the ultimate truth or Brahman is the prime goal.+

The Vedic pantheon of Gods is said, in the Vedas and Upanishads, to be the only higher manifestations of Brahman. For this reason, "ekam sat" (all is one), and all is Brahman.

Several mahā-vākyas, or great sayings, indicate what the principle of Brahman is:~

prajnānam brahma(1)

            "Brahman is Self-knowledge"

ayam ātmā brahma(2)

            "The Self (or the Consciousness) is Brahman "

aham brahmāsmi(3)

            "Self" is Brahman"

tat tvam asi(4)

            "Self' is  that"

sarvam khalv idam brahma(5)

            "All this that we see in the world is Brahman",

sachchidānanda brahma (6)(7)

            "Brahman is existence, consciousness, and bliss".

Why go round and round, by various tortuous paths:~

When the Vedas and Upanishad declare that the soul or consciousness or Atman is actually nothing but Brahman, then why go round and round, by various tortuous paths, like the blind led by the blind. One has to realize the fact that, the mind is in the form of the universe.  Trace the source of mind and realize that the source is consciousness. The mind arises from consciousness as the waking or the dream and subsides as the deep sleep.  

In Mandukya Upanishad Brahman and Atman are defined as same:~

सर्वं ह्येतद् ब्रह्मायमात्मा ब्रह्म सोयमात्मा चतुष्पात् / sarvam hyetad brahmaayamaatmaa brahm soyamaatmaa chatushpaat ~

Mandukya Upanishad, verse-2

Translation:~

sarvam(सर्वम्)- Whole/All/Everything; hi(हि)- Really/Just/Surely/Indeed; etad(एतद्)- This here/This; brahm(ब्रह्म)- Brahm/Brahman; ayam(अयम्)- This/Here; aatmaa(आत्मा)- Atma/Atman; sah(सः)- He; ayam(अयम्)- This/Here; chatus(चतुस्)- Four/Quadruple; paat(पात्)- Step/Foot/Quarter

Fragmented Verse:~

सर्वम् हि एतद् ब्रह्म अयम् आत्मा ब्रह्म सः अयम् आत्मा चतुस पात् / sarvam hi etad brahm ayama aatmaa brahm sah ayam aatmaa chatus paat

Simple Meaning:~

All indeed is this Brahman; This Atman is Brahman; He, this Atman has four steps/quarters.

While Brahman lies behind the sum total of the objective universe, some human minds boggle at any attempt to explain it with only the tools provided by reason. Brahman is beyond the senses, beyond the mind, beyond intelligence, beyond imagination. Indeed, the highest idea is that Brahman is beyond both existence and non-existence, transcending and including time, causation and space, and thus can never be known in the same material sense as one traditionally 'understands' a given concept or object.

Imagine a person who is blind from birth and has not seen anything. Is it possible for us to explain to him the meaning of the color red? Is any amount of thinking or reasoning on his part ever going to make him understand the sensation of the color red? In a similar fashion, the idea of Brahman cannot be explained or understood through material reasoning or any form of human communication. Brahman is like the color red; those who can sense it cannot explain or argue with those who have never sensed it.

The Bhagavad Gita:~ Brahman hi pratisthaham ~  Brahman is considered the all-pervading consciousness which is the basis of all the animate and inanimate entities and material. 

In Advaita Vedanta:~Brahman is without attributes and strictly impersonal. It can be best described as infinite Being, infinite Consciousness, and infinite Bliss. It is pure knowledge itself, similar to a source of infinite radiance. Since the Advaitins regard Brahman to be the Ultimate Truth, so in comparison to Brahman, every other thing, including the material world, its distinctness, the individuality of the living creatures and even Ishvara (the Supreme Lord) itself are all untrue. 

Brahman is the effulgent cause of everything that exists and can possibly exist. Since it is beyond human comprehension, it is without any attributes, for assigning attributes to it would be distorting the true nature of Brahman. Advaitins believe in the existence of both Saguna Brahman and Nirguna Brahman; however, they consider Nirguna Brahman to be the absolute supreme truth.

Chandogya Upanishad:~  One who meditates upon and realizes the 'Self' discovers that everything in the cosmos-- energy and space, fire and water, name and form, birth and death, mind and will, word and deed, mantras and meditation--all come from the Self.

So, it clearly says the one who meditates upon the 'Self' (consciousness) discovers that everything in the cosmos-- energy and space, fire and water, name and form, birth and death, mind and will, word and deed, mantras and meditation--all come from the Self. Therefore,, there is a need to know the fact that, the true self is not physical, but the soul in order to realize the fact that:  the cosmos-- energy and space, fire and water, name and form, birth and death, mind and will, word and deed, mantras and meditation--all come from the Self, which is in the form of consciousness.

Atman is Brahman. Brahman is alone real; this waking is unreal, and the three states are non-different from Brahman.

Whatever is, is Brahman. Brahman itself is absolutely homogeneous. All difference and plurality are illusory."  Brahman is not a person, as the Absolute is not this. But if one wants to call it God or ParamAtman, then fine. But it is not a person. Personifying it can make it difficult to understand the truth, which is beyond the form, time and space.

To realize the ultimate truth or Brahman is the prime goal. 

All the scriptures indicate that Atman is Brahman, and Brahman is the ultimate truth. Therefore, consciousness, which is in the form of consciousness, is the ultimate truth.  Thus realizing the ultimate truth is the prime goal.   A well-directed inquiry, analysis, and reasoning will lead one to his nondual destination. : ~ Santthosh Kumaar
