Love Letter- more

I write to that light within me which illuminates me so completely, my only complaint ------- why is the flash so fleeting?

"When two souls, which have sought each other for,however long in the throng, have finally found each other...a union, fiery and pure as they themselves are...begins on earth and continues forever in heaven.This union is love, true love,...a religion, which deifies the loved one,whose life comes from devotion and passion,and for which the greatest sacrifices are the sweetest delights.This is the love which you inspire in me...Your soul is made to love with the purity and passion of angels;but perhaps it can only love another angel, in which case I must tremble with apprehension."
How can I capture the experience?
