"DVI" (Dvaita) means two. DVI"(Dvaita) connotes dual existence.+

In India Advaita and Dvaita is a merely religious traditions, which they inherited from their ancestors. No one questions their validity because it is considered blasphemy to question their religion, their Guru, and Godmen or the pundits. 

People who are attached to their religious code of conduct and trying to preach Advaita, that is mixing the individual life, and the concept of God and all mixed up hotchpotch religious doctrine and feed the seeking people are themselves not aware of the fact that the individuality and their worldly life is part of the illusion. 

Advaita and Dvaita are not some philosophies. Advaita is the nature of the Soul, which is present in the form of consciousness. Dvaita is the illusory nature of the Soul, which is present in the form of the world in which we exist.  

The world in which we exist is a dualistic illusion. The dualistic illusion appears as a waking or dream (dvaita) and disappears as deep sleep (Advaita).  

From the standpoint of the Soul, the dvaita (duality) is an illusion. In reality, nothing ever existed; nothing exists and nothing ever exists at any point in time because the dualistic illusion has no value.

"DVI" (Dvaita) means two. DVI"(Dvaita) connotes dualistic existence.

"Advaita” means one without the second. "Advaita" is a non-dualistic existence.

Advaita is real and eternal and the Dvaita of these two is non-existence. 

Sage Goudpada: ~ To establish the truth of Advaita (Non-duality) by sheer reasoning alone. He begins by defining "What is real?" "What is unreal?" etc, because that is the right way to discuss or teach. People must first know what they are talking about. (Manduka Karika)

Sage Goudapad:~Duality (dvaita) is for the unwise, non-duality (Advaita) and undifferentiated Reality is for the wise and difficult to grasp.

DVI"(dvaita) is dependent on Advaita for its existence.

"Advaita” is the nature of the Soul. “Advaita” is the Soul itself. “Advaita” is permanent and eternal. "Advaita” is birthless and deathless because it is a formless, time, and spaceless existence.

"Advaita” is the fullness of the Soul, which is present in the form of consciousness, without the division of the form, time, and space.

DVI"(Dvaita) is present in the form of the mind. The mind is present in the form of the universe. The universe appears as a waking or dream (duality) and disappears as deep sleep (non-duality). The waking is a parallel dream and the dream is parallel waking.

DVI"(Dvaita or duality) is an illusion and impermanent. DVI"(Dvaita) is dependent on the Advaita for its existence.

Remember DVI"(Dvaita or duality) is the ‘I’. The ‘I’ is the mind and the mind is the universe. The universe is waking.

Remember- “Advaita is the Soul, which is present in the form of consciousness.

The world (Dvaita or duality) in which we exist is merely an illusion created out of the Advaita (Soul or consciousness). Therefore, hold on to the “Advaita” which is real and eternal, and mentally negate the world (Dvaita or duality) in which we exist by realizing the world (Dvaita or duality) in which we exist is nothing but the Advaita.

The Soul becomes Dvaita (duality) in waking. And the Soul becomes ‘Advaita” in deep sleep. The one that becomes the waking and the one that becomes the dream and the one that remains without the waking or dream is the Soul. so, no second thing exists other than the Soul, which is present in the form of consciousness. Thus, the Soul, which is present in the form of consciousness alone, is real and eternal. The Soul is the ultimate truth or Brahman or God in truth.

“Neti ~ Neti ~ Not this, Not this, Not that ~ ” This does not mean that Advaita is a negative concept or a metaphysical abstraction, or a nonentity, or a void. It is not another. It is all-full, infinite, changeless, “Self’-existent, “Self’-delight, “Self’-knowledge, and “Self’-bliss. It is the essence. It is the essence of the knower and the known.

When the illusion (Dvaita or duality) is negated ‘Advaita alone prevails as the ultimate reality. 

Remember:~

All the Advaitic teachings of the Gurus of the east and west are nothing to with the Advaitic wisdom of Sage Sankara.

Remember:~

Without Sage Sankara there is no Advaita because he is the more profound of the Advaitic wisdom.

Advaita is universal. Advaita is not for sale. Do not buy Advaita from the spiritual supermarket. Advaita is the nature of the Soul, the Self. The world in which you exist is created out of single stuff. That single stuff is consciousness. Knowledge of the single stuff is Advaitic wisdom.

Advaitic truth is very simple, but it is very difficult to realize because you have accumulated mental garbage from different sources in the name of Advaita. Until you discard all the accumulated knowledge you will never be able to realize the Advaitic truth, which is beyond form, time, and space.

The Advaita is the nature of the Soul, the 'Self' shines on its own awareness when wisdom dawns.

The Advaita is the Soul is the cause and the support of all that exists in the world in which we exist. Advaita is the nature of God, the Self.

The Advaita is present in the form of consciousness. Advaita is the root element of the universe. From the Advaita, the universe comes into existence. In the Advaita, the universe resides. And into the Advaita, the universe is dissolved. The Advaita is the parent of all that is there. :~Santthosh Kumaar
