To come to truly understand the hidden truth of all things. You must walk the path of unknowing by which you surrender your intellect to the indwelling of the Holy spirit. If you desire your mind to be filled with heaven, such that you taste that land, which eye has not seen, and ear has not heard, you must close your senses off to the world and allow the Holy spirit to empty you of all things. So he might fill you with his secret music to come to rest in the love, which you have not to come to connect with the God within whom is pure love. You must die to all things and surrender your will with complete abandonment. The old self must die so that Christ can be resurrected within.
