Everything is energy, and the world is like a stream of continuous collective symphonies. In that sense, the energy that each Crystal represents is its continuous individual song, the Crystal is the instrument (physical embodiment) that is playing its song (energetic embodiment), and where as a Crystal with inclusions is like having different instruments playing its song together. As such, Crystals most of the times are wonderful together as group, and while some may compliment more efficiently together than others, they harmonize and synchronize together to create beautiful symphony.
Each of us is our own unique continuous individual song as well. At times, it feels like a Crystal just calls to you and vice versa for some reason. That very reason may be an internal calling that we have reached a point within our song that needs fine tuning and enhancements, and we are intuitively drawn to the Crystals that call to us, as we recognize subconsciously that they would harmonize and synchronize well with us together into creating our own unique marvelous symphony. Thus, Crystals will go where they are needed at the proper time, when their silent calling is answered by those who are meant to hear it.
