When one transitions later in life, there is a wonderful opportunity to realize that all fear is brought about by attachment to desire, in other words, that if I manage a company, and have a house, and bank accounts, and reputation, and friends and family, that there is a strong possibility that I will "lose" many or all of these things if I cross genders. The realization that I consciously give up those attachments, and consequently lose my fear of losing them, can be life changing.
If one choses to see this during transition, then one can see the 4 noble truths lived out in one's life during transition. The feeling of being free from fear can give one the assurance that "all things are possible" and that if one can cross something so basic to our culture as gender then one can do anything, or nothing....whatever the case.
So in this sense transition can be a vehicle to enlightenment and becomes entirely necessary for some of us. Hooray!
