Does the Consciousness vanish when the objects of consciousness are removed?
According to Buddhism does the Consciousness vanish when the objects of consciousness are removed?

There are different types of consciousness, or different things which are all translated as "consciousness".

I gather from answers and comments to this question that:


There are five sense-consciousness (e.g. eye-consciousness) which arise when there's a sense-object and attention
There's a sixth, analogous to the five, where the mind becomes conscious of thoughts (like the eye becomes conscious of sights)


Later forms of Buddhism posit two further consciousness (see e.g. Eight Consciousnesses).
I suspect that early Buddhism might do something similar but perhaps using different names -- my (poor) understanding is that the function of the (early) sankhara aggregate might be similar to the function of the (later) ālāya vijñāna consciousness.

So is the author right or wrong?

I think he's right that there's no sense-consciousness when there's no sense-object.

Wrong in that there are longer-lived aspects of the mind.

Also I think that the (or a) difference between Buddhism and Hinduism is that consciousness, whether short or long, isn't viewed as "self" or "soul".

What is the Buddhist take about the existence of consciousness apart from human brain?

I don't know, "sentient beings" aren't necessarily human -- they may be animal, ghost, or in a hell or a heaven.

I think that Tibetan Buddhism also posits a Bardo, and existence after death and before the next birth, whereas I think that Theravada assumes that consciousness exists in a body.

Does the Consciousness exist in the universe apart from living beings?

I don't know; that sounds like it might be Hindu "Brahman" -- I don't think it's a feature of the Pali suttas, maybe it's (I don't know) in any of the later doctrines.

Also there's e.g. Brahma (a God), not to be confused with Brahman -- Brahma exists (according to the suttas) -- probably a living being but not a human being, a human body.
