The ultimate truth or Brahman is one without the second, the one is not in the sense half or two, but the one that remain forever One, without the second.

Buddhist teaching has itself become a kind of interactive and self-evolving process, much like its idea of pratityasamutpada. However, the end goal is still Nirvana, which is an experience ultimately beyond all concepts and language, even beyond the Buddhist teachings. In the end even the attachment to the Dharma, the Buddhist teaching, must be dropped like all other attachments. The tradition compares the teaching to a raft upon which one crosses a swift river to get to the other side; once one is on the far shore; there is no longer any need to carry the raft. The far shore is Nirvana, and it is also said that when one arrives, one can see quite clearly that there was never any river at all.

Most of the dualistic sages approach was more practical, and they stuck with the reality of the world, they took it as real.  Whereas Sri, Sankara says: one must first know what is before him. If he cannot know that, what else can he know or understand? If he gives up the external world in his inquiry, he cannot get the whole truth.

Sage Sri, Sankara says -(VC)-63. Without causing the objective universe to vanish and without knowing the truth of the Self, how is one to achieve Liberation by the mere utterance of the word Brahman? — It would result merely in an effort of speech.

The scriptures and theories and teaching based on the ego are not the yardstick. Using them as yardstick to understand and assimilate the truth will lead one towards pursuit of arguments. Seeker of truth has to discover on his own, the truth of his true existence by inquiring “what is mind?” and “what is substance of the mind?” and move forward.  

The ultimate truth or Brahman is one without the second, the one is not in the sense half or two, but the one that remain forever One, without the second.  The consciousness is all pervading. There is no place where consciousness is not.

Consciousness is in everyone, consciousness is in everything .consciousness is one behind many. Consciousness alone is. It means the universe is the visible form of consciousness.
