If all phenomena are equal (since all are empty), then it is no more or less advanced to choose and use a phenomenon that is considered "positive" or "negative" as an object of meditation. And it should not matter if one experienced positive or negative "arisings" since equanimity is the key anyway. The object one chooses will assist one to overcome the extreme that one will deal with. If one chooses a "positive" phenomenon and achieves eqaunimity then one has overcome attachment, if one chooses a "negative" phenomenon and achieves equanimity then one has overcome aversion. For some people excessive attachment is their problem and thus they must deal with objects of attachment and for others it is excesive aversion that is the problem, so they must deal with objects of aversion. It has nothing to do with levels of experience or capacity, it just has to do with ones current karmic preponderence.
So, nothing to pat oneself on the back about there I am afraid, because (based on what you are saying and how you present it) it sounds to me that the only thing that happened to you was an increase in pride regarding your apparent spiritual capacities.
Dog shit and roses both have a scent, but it is our minds which smell sweetly or stink!



How true.
