I think you are approaching thoughts of divine order.  I try to imagine existence as a giant computer that runs on electricity.  Positive and negative energy from organic life is transferred up through the different dimensions and altered as needed to accomplish a task or criteria.  Thirteen would be the highest digit in a divine mathematical system and imagine the different dimensions as RAM.  Starting at the most base function giving a positive and negative value is human life or other organic sentient lives.  Values are returned to a higher dimension upon ascension and the process continues up and up through the twelve different dimensions ultimately hitting the 13th dimension which would be "God" or "Prime Creator" or whatever deity you want to imagine sits on top of the mountain.  So the realms that can be influenced and relayed to the top spot would be a total of twelve.  Starting from the top you get 12 in the top dimension.  The first twelve functions in the processor or whatever, let's call them first born.  The 11th dimension would be 12x12.  The 10th dimension would be 12x12x12, so on and so forth down to human lives which could be considered a quantum calculation.  You give a net positive or negative charge based on all the calculations and exchanges you make in life.  Then the next plateau is essentially the same thing in perpetual motion through each dimension until it gets back to the top.  The theory that there is an infinite amount of existences and realities would require an infinite number of copies of infinite clones of yourself doing infinite instance of the same thing and each thing you could be doing at any given moment.  So it is only logical that there are much more than one copy of yourself that isn't directly influencing another dimension and is set on an infinite number of paths in infinite directions and realities.  It's kind of mind boggling to think about, but the point is you only need to focus on doing what you feel compelled to do in this existence and reaching higher consciousness if you want to try to comprehend things beyond physical capabilities.  If you work out the math on the 12 dimension thing,  12^12 = just under 9 trillion 3D realities.  Everything must have a beginning and an end so infinity is more of a concept of human limitations on calculations.  I don't think it should be considered a number, but more of a flow of energy.  Energy is never created or released and it is self contained in an environment  that perpetually reuses it.  I find it interesting that computers are based on the same logic and perhaps it really is all just one giant matrix.  You can look through history as 13 being the divine number and the basis of the number of dimensions.  The painting of the last supper references the zodiac and divine numerology as well.  Look at the cloaks of Jesus and Mary and notice how they alter from the typical male and female colors we are acquainted with and consider that balance could be the ultimate purpose of existence.  It also makes you wonder if it does grow, are really seeking ascension or descent into our own creations of reality thus altering divine order and making a 14 reality which would destroy the entire way of existence.  What happens when a 3D reality creates an infinite amount of 2D realities.  What if the 2D realities become sentient and manifest and infinite number of 1D realities that become sentient and we hit 0 and basically implode an already catastrophically unbalanced system?  Maybe the point is that computers should never reach quantum capabilities in a 3D existence or it breaks the higher dimension.  Infinite possibilities would mean it has happened before and destroyed all other existences, so existence can not be infinite.
