to realize the indivisibility of your awareness with your spiritual mentor is not to recognize two separate things mixing together and becoming indivisibly merged, as when water is poured into milk. To realize the nature of your awareness is to realize that your own awareness is your spiritual mentor. This has always been the case, but now you recognize that primordial reality. If you want to learn about two things merging, study science. To understand primordial indivisibility, study the nature of the mind-itself. –Gyatrul Rinpoche
