If I have the idea of an "apple" or its taste,
- is the idea as real as the apple itself?
Specifically
- do the objects of the 6th consciousness depend on anything except the 6th consciousness?
In normal philosophical terms
- does the idea depend on the mind having the idea, in order to exist?
I think these are all equivalent questionquestions, because causation is the conventional truth - ideas, the ultimate - no causation, and the middle - the buddha nature or mind-body.
