On the matter of consciousness, I recommend checking out Bhikkhu Nanananda's...Nibbāna Sermon 7http://www.beyondthenet.net/calm/nibbana07.htm
The point we wish to stress is that consciousness has in it the nature of reflecting something, like a mirror.
Now vi¤¤àõaü anidassanaü is a reference to the nature of the released consciousness of an arahant. It does not reflect anything. To be more precise, it does not reflect a nàma-råpa, or name-and-form. An ordinary individual sees a nàma-råpa, when he reflects, which he calls `I' and `mine'. It is like the reflection of that dog, which sees its own delusive reflection in the water. A non-arahant, upon reflection, sees name-and-form, which however he mistakes to be his self. With the notion of `I' and `mine' he falls into delusion with regard to it. But the arahant's consciousness is an unestablished consciousness.
We have already mentioned in previous sermons about the established consciousness and the unestablished consciousness.[ix] A non-arahant's consciousness is established on name-and-form. The unestablished consciousness is that which is free from name-and-form and is unestablished on name-and-form. The established consciousness, upon reflection, reflects name-and-form, on which it is established, whereas the unestablished consciousness does not find a name-and-form as a reality. The arahant has no attachments or entanglements in regard to name-and-form. In short, it is a sort of penetration of name-and-form, without getting entangled in it. This is how we have to unravel the meaning of the expression anidassana vi¤¤àõa.
But all his sermons string in to other another so you may also want to go backwards or forwards a bit too.
