Why did Adishankaracharya said " The world is not real and is an illution, at the same time it is not.......?

Adishankaracharya is personification of wisdom himself. At just 32 years of age whatever he has compiled whether any one has the capability I doubt. He is therefore an extra ordinary person.

He has understood that if universe had to be explained, it has to be explained only due to a single cause, for, if multiple causes existed, then the cause of those causes will have to be found and this process will go on backward till all converging into a single cause. There is logically no alternative. In fact, he felt even that single cause can not be called 'cause' in the ordinary parlance, because one will then spring to ask what is the cause for that cause! Therefore, he made a simple but eye-opening statement that only one exists which is cause as well as effect! That one thing has no second he stated. He, however made this statement after examining the vedas which were unanimous in one thing- "Sat eva sowmya idamagraasit ekamevaadvitiyam. (Dear child, only one Reality existed from the very beginning, without a second).

So far so good. But he had to also explain what is this world wee see. Surely that can not be untrue! He made use of the "next veda statement-"Sa ekshata bahusyaam prajaaiva (That solitary Reality desired let me be many). Thus that variety is what has become universe. As it is not independent of Sat, it has to be relatively unreal (impermanent or unstable and not a lie) to the cause (brahman) which is Real (permanent and eternal) in originality.

If the above had not been there, but God is different and living beings are different, then there will be conflict and everything would have been annihilated, as they share nothing in common to work in unison, is it not?

The one thing that remains unanswered, which is the root cause of all conflicts is-why that Sat wanted itself to become many?

The Advaithis admit it is not known. Visistaadwaithis go to answer this as 'Leela' (Play of that Sat)! But why that Leela? that to with the entities made of itself?

If there had been answer discovered, the world would have ended, because there would be no unresolved riddle then! Probably that is which time everything collapses back to the single entity- the big-crunch, I would be grateful to know!.

Truth does not only remain eternal, but also does not change.

This World is changing constantly, so untrue. It has ingredients which are Short-term and the same as long-term is what we must aim for. Vedanta says, 'What is pain at start, is pleasure later'. So every vise as short-term is good for this world, but bad as Long-term goal. Our Soul is long-term. So physicality is true in this world, but there is its image of 'Cause & Effect' which is true.

Sankracharya says subjective experience. No contradiction.

World that exists created by mind.

When man get moksha, world that exists disappears. Only true for liberated man not others.

For others world exist no matter how many attain liberation.

Did amma make it clear for you son ?

I am Brahman

the world is a projection of mind.

I live for the Beloved Brahman.

the world exists for me!

May be because

the ultimate existential truth of the world is unknown at the worldly level of consciousness.

There is something called Vyavaharika Satyam(relative truth). An there is something called Paramarthika Satyam(absolute truth).

Sun rises in the East. We have read this statement all our lives and it is true. But it is just a convention, and not absolutely real and true. It is actually earth that rotates round itself revolving round the sun and we see day and night. But at the same time it is not wrong to say Sun rises in the East as per the popular convention. This is Vyavaharika Satyam. Relative Truth employed so that a reasonable discussion can happen with things that we commonly understand. The purpose of this Vyavaharika is talked so that we can start discussion on common ground or terms that we commonly agree upon and then discuss about higher things and higher concepts like Paramarthika Satyam. This is the style of Vedanta.

Other thing is, as long as you are in a dream, and experience the dream, that dream is real for the dreamer. Only when one wakes up, he/she automatically knows for himself/herself that what he/she has been experiencing is unreal(when compared to waking world). Similarly Vedanta says, though the experience of a universe as separate from us(common feeling of an observer that we are, and the universe around me that I observe) is only real as long as you don't realize that you are Brahman, the absolute reality - Paramarthika Satyam. Just like dream world has reality till one is experiencing dream, and has become unreal once we woke up, similarly once we realize Brahman, we will come to know that this universe that we experience in waking state, and also our concepts of a separate God above in heavens - all these melt away in absolute reality.

This is what Adi Shankara points out - Brahma Satyam Jagan Mithya.

Now there is great deal of philosophy with this word Mithya. It is commonly mistranslated as illusion as if it is seen yet it doesn't exist. No, this is not correct translation. This is because of limitation with English language, we can't express this word easily. So first know that there is no equivalent of word Mithya in English. Before understandinh word Mithya, it is also important as to what is Real and Unreal according to Vedanta.

Satyam or Sat - Trkalepi Tishtati iti Sat. That which exists in all three periods of time(past, present and future) is defined as Satyam or Real.

Asatyam - Anrutam - False or Unreal. That which never existed. Like horns of a hare. Or son of a barren woman(meaning woman who cannot give birth to child due to some medical problem, so to say). Can these entities exist ever? So these are called Asatyam or Anrutam or Unreal, which are non-existent in the 3 periods of time, as per sanskrit meanings.

Meaning of Mithya - This is NOT an illusion like what a magician creates and yet unreal. Nothing like that. Definition is - Anything which has no independent existence, or whose existence depends on something else, this is called as Mithya. We say, All is Brahman. If you say, this universe is being seen by me right now, then Vedanta says, yes it might be true relatively when you view it with your 5 senses, but its existence depends on Brahman(identical with Self that you and I are, according to Adi Shankara). Once you know yourself, then you will experience this oneness with all Existence. Just like the dream was known unreal when you wake up, similarly universe will be known to be unreal once you wake up from this dream called life.This is the experience of Advaita(Non-duality, which is the nature of Self).

When explained in terms of english, it is neither real(as universe is not an independent existence, an observer is required to say it exists) nor unreal(seeing that you perceive a universe). This is what Mithya is. At best it can be said as neither real nor unreal or Anirvachaniyam(unexplainable but undeniable in relative reality).

Hope this helps to some extent.

Shankracharya first denied everything except Brahmm but later accepted Adi-Shakti and wrote beautiful verses for Her.

i think this shows the spiritual evolution of Sankra... he corrected his own mistakes
