Buddhist Idealism speaks only of ideas.+

Buddhist Sunyavada is incongruous because every thought has its opposite every word is tied to its coordinate for all thought and speech can only operate under such dualism. Hence, taking the most fundamental word, existence its implied opposite non-existence is also there, and vice versa. Therefore, the Sunya "non-entity" is meaningless without "entity". Both are there.

Buddhist Idealism speaks only of ideas.

What about the knower of these ideas?

Buddhist Nihilism does not ask "What is meant by Nihilism?

It is a thought.

There must be a thinker of this thought.

Bhagavan Buddha kept silent, refusing to answer questions on the ultimate. Therefore, he was the wisest man in refusing to commit himself.

When you say "Nothing is" what is the meaning of "is"? "Sunya" is something that exists: you cannot prove that consciousness does not exist.

Sunyavada Buddhism strongly holds that the ultimate is but a void, with nothing existing, not even the Soul, the ‘Self.

Hume and Sunyavadin Buddhists declared the non-existence of Entity, a Void. This is just as much unwarranted finality, for it means you are viewing it from a particular standpoint as to declare its existence. Silence alone is called for. The absence or presence of the objective world and even existence and non-existence is always referred to as Seen only; it still leaves the Soul, and the witness is untouched.

In reality: ~

Where is the body?

Where is the mind?

Where is the world?

The void; or despair in the true Self, which is the taintless Soul, is present in the form of consciousness. They are or have become the consciousness.

One thinks there is a mind when he has thoughts, but when thoughts are not considered different from the consciousness, which is the true Self, then where is the division into, waking, dream and deep sleep, etc.

Void implies duality: the universe may not exist, but the thought of the second is there. If one knows there is a Void (emptiness/nothingness), then there is something there to be known and know. They are or have become consciousness.

All these appearances are merely an illusion that comes and go; hence meaningless to the formless Soul, the Self.

The sun, the moon, the stars, planets shine because of the Soul or Spirit.

The Soul shines and all things else shine as a result. Everything in the universe reflects but that light of the Soul which is present in the form of consciousness. Merely knowing the truth is not enough to escape from the tangle of illusion.

One who realizes the 'Self' discovers that everything in the cosmos-- energy and space, fire and water, names and forms, birth and death, thoughts and words and deeds is merely an illusion created out of consciousness.

All is consciousness. The whole universe is consciousness. From consciousness, the universe comes. When the universe disappears, consciousness still remains without form, time, and space.

Sage Sankara disagrees with Buddhists who say, there is nothing - a nonentity. Sage Sankara believes there is some reality, even though things are not what they appear to be. If one knows the truth, he will know what to do to find inspiration for action. The seeker of truth‘s subject is to know what is it, that is Real.

Buddhism says: all things are illusory and nothing exists. However, Advaita avers that it is not so. It says that the universe, of course, is illusory, but there is Brahman (consciousness), that exists forming the very substratum of all things (illusion or universe). ~Santthosh Kumaar
