From Meister Eckhart’s The Talks of Instruction (M O’C Walshe translation):
Therefore start first with yourself, and resign yourself. In truth, unless you flee first from yourself, then wherever you flee to, you will find obstacles and restlessness no matter where it is. If people seek peace in outward things, whether in places or in methods or in people or in deeds or in banishment or in poverty or in humiliation, however great or whatever kind all this may be, this is all in vain and brings them no peace. Those who seek thus seek wrongly; the further they go the less they find what they are seeking. They are like a man who has taken a wrong turning : the further he goes, the more he goes astray. But what should he do? He should resign himself to begin with, and then he has abandoned all things. In truth, if a man gave up a kingdom or the whole word and did not give up (him)self, he would have given up nothing. But if a man gives up himself, then whatever he keeps, wealth, honour or whatever it may be, still he has given up everything.
