Nothingness is the nature of the Soul, the Self. +

Nothingness/ emptiness/ Sunya/ void is one, and the same thing.

Nothingness is the fullness of consciousness without the illusory division of form, time, and space.

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 consciousness.

One thinks there is THE 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 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
