We think life exists only on the physical plane, but there are many unknown dimensions of existence in which many beings live and thrive. Just like we have soul mates on this plane, we also have many soulmates on these other dimensions.
In this painting, Mandalas represent different dimensions of existence and the trees within these Mandalas represent the growth we can experience in each of these dimensions.
Wherever the soul takes birth, either on earth or other dimensions, it does so, to learn some lesson that can be learned in that dimension. Growth is the essence of life. We come, we learn, we grow, and we go. This cycle goes on and on, he soul learns all it has come to learn and when it is ready it returns back to the ultimate Divinity.
