Plato mixed some of those Indian ideas with his own. ***

PLATO:- The Greeks got their best ideas in philosophy from India, some of their thinkers like Pythagoras having traveled to India. Plato mixed some of those Indian ideas with his own. Who has seen that substance called the "soul"? The Platonic dualism of soul and body is speculative, not philosophic. It is like Ramanujaism. Plato rose to the truth that the world is an idea, but he did not go beyond that to the ultimate, i.e. that the idea itself disappears in Brahman.

LEIBNIZ's monads have each a window through which they look on an independent material world. It is like Ramanuja's and Madhva's belief in the multiplicity of souls. 

SPINOZA'S doctrine of mind and body being two aspects of the same unknown reality, substance, is the equivalent doctrine of Ramanuja's Visishtadvaita. 

RAMANUJA believed in a plurality of minds or selves and also in prakriti matter. The latter he thought ultimately existed in the form of particles similar to our atomic theory. But recent science has killed the atomic theory and matter has vanished with it. Hence modern Ramanujists fear science and try to avoid it. 

Science investigations into objects; they are useful in the practical world and scientific inventions are very helpful in practical world.  The science, scientist and its inventions are part of the illusion. The ultimate truth or Brahman cannot be got from laboratory condition because the ultimate truth or has to be got   only through deeper thinking and reasoning.  Intellectuals are deluded that science is the correct path to the final reality, but they have to accept the fact that,  the truth of the whole universe is impossible from the external source, but until one investigate the innermost self  the truth will not be revealed.   

No one has ever seen the awakening of consciousness. No one has ever seen the first man or the first animal. No one has ever seen the god creating the world.  Such talk is not philosophy but hypothesis.

When the yogi sits down to meditate, he is thinking first of sitting, i.e. his body; next he says "I do not want such and such thoughts," i.e. he is already thinking of those thoughts. Thus, he is thinking of the object (form) never of the subject (formless). 

Hence Ashtavakra says: ~“This is your bondage, that you practice Samadhi (meditation or trance)"

Without imagination   has the thinker-- what do one get with thinking—he can get only a thought. Meditation is only an effort of the ego; it is an imagination, an idea.

When soul’s attention is riveted on the illusory object, it forgets itself. This is true whether an external object or an internal (one) idea. When soul is absorbed in the illusion it forgets its formless nondual true nature. When one inquires who the witness of the three states, he becomes aware of the existence of the existence of the formless witness of the three states apart from the three states, which is eternal.

When one cannot see into a man’s mind he can only say he cannot accept that there is a multiplicity of minds, he can only see his lips moving but not his mind moving. Hence he can neither accept nor deny this doctrine of multiple Jivas. It is an unproven hypothesis.

To say that each mind is different is unproved because you have never seen the mind. Can one say where it starts and stops, have you measured its thickness? All is supposition, not proof. 

Who else but the self could have imagined the objective world? dualists  see God as the imaginer, but where is the proof. Nobody has seen God creating. one has  seen no other creator, whether God or angel. The only self is left. Therefore,  the self is the creator , because imagining means creating. The dualists  imagine the existence of god and then go on talking about such imagined God. .  God has no  meaning  because it is mere  an imagined  idea. What is an idea? An imagination. So God has no proved existence beyond that of an idea.

Where people cannot and do not think, they follow others. A Gnani will see the world and get to know it is only appearance. He is not blind; he sees three states or objects as it is, but he knows it is only falsehood. Just as one sees a mirage, the Gnani sees the mirage of this universe too, but he is not deceived by it. So long as one is ignorant, he will have the idea that God has created this world because the causal notion will be there. Nobody wants to suffer, and during the notion that suffering can be got rid of by appealing to God these wishes will sway the mind to believe in God. For them religion will arise, but for the man who wants the truth, religion offers no consolation.

Dualist sages say God cannot exist without attributes. Then they are making God as an object whereas God is the subject. Attributes can only be seen in the objective world. Causality appears in the duality, but when one goes deeper into the matter even there the causality disappears.  

Kabir views humanity as being caught up in the illusion, searching for Ultimate Reality in all the wrong places, always seeking It outside of ourselves in various rituals, temples, forests and mountaintops, not realizing That for which we seek is already hidden within us. 

The ultimate truth or Brahman (God) dwells within the three states like fragrance in the flower; Musk lies within the Musk-deer yet seeks it afar." Until one trace the truth within the three states the illusion of birth, life, death and the world is experienced as reality.  ~Santthosh Kumaar

The world is both real and unreal. It is real because it is a manifestation of consciousness, but is unreal, in the sense, that it is not absolute and eternal like consciousness itself.

Peoples approach is more practical, and they stuck with the reality of the world, they take it as real. That is why all the confusion.

That is why 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.

65. As a treasure hidden underground requires (for its extraction) competent instruction, excavation, the removal of stones and other such things lying above it and (finally) grasping, but never comes out by being (merely) called out by name, so the transparent Truth of the self, which is hidden by Maya and its effects, is to be attained through the instructions of a knower of Brahman, followed by reflection, meditation and so forth, but not through perverted arguments.:
