What does this mean? So hard to understand. Thanks?

Searle further argues that if consciousness is to be considered a feature or effect of brain processes, we must be clear to understand that it is not an effect separate from and posterior to the brain processes causing it. For Searle, this view of cause and effect is misleading when applied to consciousness because it unavoidably leads to dualism, which is untenable. Instead, Searle argues that the relation between consciousness and its causal brain processes involves a kind of non-event causation such as would explain the fact that gravity (a non-event) causes an object to exert pressure on an underlying surface|||The intricate philosophical meaning can be known only after reading in between the lines several times. At one reading, it is difficult even for wise philosophers. One has to read at different intervals. Because our mind functions at different levels of efficiency.|||I'm far from an expert but what I think this is saying is that consciousness is not neccesarily an effect of brain processes. To say that there is a cause effect relationship is inaccurate. Finally he is equating the relationship between brain processes and consciousness to the relationship between gravity and for example a cup exerting pressure on a table
