Be faithful to soul. You may not know where you're going but that isn't the point. The real point is to open up to what is being asked of you. To be faithful as you are asked to move with a soulful perspective - one that is larger than one could imagine. One that makes sense in its own way.
Wolfgang Giegerich writes in many ways about the soul having its own logic.
We move toward something or someone thinking that he/she/it is this/that/or the other only to find out that we need to leave that vision behind through a negation of what we see and open to what really is. It isn't, though, that our journeys are insubstantial or not worthwhile if what we think "is" and it "is not". We learn, rather by this journey to this/that/other and the act of negation to know more of what really "is." We cannot learn otherwise.
Being faithful to always knowing that we reside in soul, in this sense, as distinct from soul residing in us offers a very different perspective in life. The soul is always thinking in its own way - not with rational logic, but with soulful logic, with a logic that invites us to a fuller expression of life.
