That an absence be directly
contemplated, such is impossible. What is however possible is "to get lost" in one's own fantasy/idea.
Contemplating the aggregates is just this, namely contemplating the heuristic categories of experience. This entails the cognition of "I" and "mine" (or "self") as mere ideas because there is nothing that can be found except these categories of experience and their continuous arising and cessation.
In this sense the Buddha's teachings about the aggregates is a affirming negation of "self". "self" is implicitly negated and the aggregates are "put in its place" (metaphorically), i.e. affirmed. Implicit "anatta" teachings.
Now ... in this context ... affirming (in addition to the aggregates) "buddha nature" IMO necessarily re-establishes what has been implicitly negated before.
