The knowledge of both matter and spirit is the True knowledge. The true knowledge is Self-knowledge or Brahma Gnana or Atma Gnana.
That alone is called ultimate truth, which is a fact that can never be changed under any circumstances. One must make an effort to know the ultimate truth or Brahman. The soul, which is present in the form of consciousness, is there always. Consciousness pervades in everything and everywhere in all the three states. Consciousness is the permanent thing and all else is a mere illusion.
There is nothing new to be acquired; only they have to be sharp enough to grasp and understand and assimilate it, when told about it. But there is a difference between understanding and realization. Effort is required for this understanding only, whereas once understood no special effort is needed to remember his understanding: Till then he only has an idea of the soul, he only partially understands it. But once he thoroughly grasps what it is and that all these things are soul, he will then constantly find it present everywhere without further effort, because he will perceive the ultimate truth by understanding, even in the midst of worldly existence.
When there is only one thing that is soul, then there is nothing to change, nothing to appear or disappear; when one speaks of remembering or forgetting soul that implies he believe in the existence of something else, i.e. a second thing, which is to be remembered. That would show he doesn't know that all is one. But knowing it, there is no second, consequently no intermittent perception of the soul, but a permanent effortless understanding and assimilation that it alone is.
When one gets a mental glimpse of truth he has to try to repeat it a number of times in order to establish it. The soul, the innermost self must raise itself by it self.
It is necessary to repeating the same truth again and again till it becomes reality. One needs to constant reflect on the subject until he gets a firm conviction of what is what. Words are needed until one gets firm conviction of ‘what is what’. People need reading and hearing the words to think deeply and reach the ultimate end.
The difference between a physical truth and a spiritual truth, the former can evolve or change; the latter is ultimate and final.
The seeker has to verify and accept the truth and reject the untruth. When Buddha verified Vedic religion, god and scriptures and found them they are not the means to acquire self-knowledge or Brahma Gnana or Atma Gnana and rejected them. Then he was on his own and found the truth through deeper reasoning and got enlightenment. Without being judgmental about your views, I am expressing my views derived from deeper self-search.
It is impossible to prove the existence of God by any reasoning: one can only believe or assume. Religious believers see visions of gods and goddesses and adepts according to their own impressions remaining unconsciously in the mind from the inherited conditioning. This entire concept based confusion and doubts are present only till the ignorance is there. Once one discovers the fact that, the self is not physical but it is the soul, the innermost self then there is no scope for duality, which he experienced as reality.
"It is this Supreme Oneness which alone is real, since there is nothing else but the Self. Verily, there remains no other independent entity in the state of realization of the highest Truth."
People believe that the teacher or the mystic or the priest has got so many followers and therefore there must be some truth in their teaching, is a common fallacy accepted by the mass due to their inherited and inborn samskara or conditioning. It proves only an ignorant can find a number of greater ignorant to follow him.
No one has seen God or world in deep sleep. One does not know gods capacities, what god can do? And, what God cannot do in deep sleep? Therefore, any statement one might make about God can be made only in the waking experience (illusion). Seeker of truth should not accept anything as truth until and unless he verifies and satisfies himself through deeper inquiry, analysis and reasoning. Belief of the god is the part of the illusion; therefore, God is only a settled fact for believers. However, for a Gnani, the god's existence is only part of the illusion. A Gnani knows nothing other than consciousness (soul) can exist in the realm of truth.
Ahum Brahmsmi (I AM BRAHMAN) – spiritually it means –Self (soul) is ultimate truth.
Sage Sri,Sankara :- Atman is Brahman – The Soul is the ultimate truth.
Bhad upanishd: - This Self is dearer than a son, dearer than wealth, dearer than everything else, because It is innermost. If one holding the Self dear were to say to a person who speaks of anything other than the Self as dear, that he, the latter, will lose what he holds dear—and the former is certainly competent to do so—it will indeed come true. One should meditate upon the Self alone as dear. He who meditates upon the Self alone as dear—what he holds dear will not perish. (8-p- -211)
The foundation of all the religion is based on the truth (non-duality) but their practice is based on untruth (duality).
Isa Upanishads indicates that: By worshiping Gods and Goddesses and going to the world of gods after death is of no use. The time one spends in ritualistic practices is wasted; one can spend same time moving forward towards Self-knowledge or Bramha Gnana or Atma Gnan, which is the main goal. One cannot reach the nondual destination by glorifying god and goddesses and by doing that, one goes deeper and deeper into darkness. It surely indicates the fact that, the seeker of truth has to drop the worshiping god and goddess in order to get Self-knowledge or Bramha Gnana or Atma Gnan.
Sage Sri, Sankara as a rationalist philosopher, in contrast to the more traditional image of him as a theologian: (Sage Sri, Sankara’s system of Advaita) is not even a philosopher dish cooked to suit exclusively the palate of the Hindu. It is like the air and the water, the common food of all men in all countries. It is ... an attempt ... at constructing a "Science of Truth," nay, in fact, it is the only attempt yet made at such a science. If rightly interpreted Sage Sankara’s teaching as food for all humanity, the universal teaching par excellence; it is not just a religion, but the religion; not a philosophy, but the philosophy; not a science, but the Science of Truth; not a soteriology, but the path to spiritual liberation par excellence, wide and deep as the ocean which contains virtually all the water of the world and in which all particular forms ultimately dissolve.
Sage Sri, Sankara' gave religious, ritual or dogmatic instruction to the mass but pure philosophy only to the few who could rise to it. Hence the interpretation of his writings by commentators is often confusing because they mix up the two viewpoints. Thus they may assert that ritual is a means of realizing Brahman, which is absurd.
In the realm of truth the three states are mere illusion created out of consciousness. The dream becomes unreal when waking takes place.similarly the waking becomes unreal when wisdom dawns.
The the waking experience itself is an illusion. Therefore, the experience of the birth,life,death and the world experienced within waking experience is bound to be falsehood.
How do the mystics or yogis know they have experienced the whole, when they themselves exist within the whole? There is the proof they have seen it? When they say, "I know from experience" they merely mean, "I think so.
In the realm of truth the man and his experience of the world are mere illusion created out of the soul, the innermost self. Moreover, the waking entity is not the witness. The one, which sees the coming and going of the three states is not the waking entity but the formless soul, the innermost self. Thus, there is no physical apparatus to experience the bliss or any sort of experience. If mystics experiences bliss, they cannot be wakingless or dreamless, for who is having the bliss? Moreover, if they retain the waking or dream they cannot know the Ultimate truth or Brahman, the whole. Whatever they experienced as reality only in illusion and illusion is a myth. Whatever, prevails without the illusion or myth is ultimate reality or Brahman.
