The teacher is the person who ought to know.... He ought to know by a glance at your face and put you on [your path]. We grope about and struggle here and there and do all sorts of things and make no progress until the time comes when we fall into that life-current and are carried on. The sign is that the moment we are in that stream we will float. Then there is no more struggle. This is to be found out. Then die in that [path] rather than giving it up and taking hold of another.
