The mustard seed concerns faith. Faith is the area or Sagittarius or the Ninth house. A pure faith, ostensibly, is required to see the kingdom. A fractured faith, on the other hand, sees other things and mistakes them for the kingdom. Therefore, the fourth house would be the disruption experienced until nothing is left potentially but the kingdom--a hard road, to be sure.

Faith of a Mustard Seed

So how would that pertain to the mustard seed and the understanding of the Kingdom through the expression of time and elements, if my hypothesis is correct?  

 In other words in my chart I think I showed you the 4th house, and that is where on a calendar 7/22 or the day that is between Cancer and Leo.  The 4th house is in Virgo, Mercury would then apply to one of the Platonic Solids, I suppose I need to map that out first to understand it better?  lol
