Funny about spiritual endeavor:
Without a very concrete effort, you just end up as some sappy poseur and never get anywhere.
And yet exercising a very concrete effort, you just end up as some upright poseur and never get anywhere either.
If this is true, I think it is reasonable to deduce that the most important aspect of spiritual life is tying your shoe.
No one in their right mind wants to live life as a poseur.
