In life you will go through different phases, some physical and some spiritual. If during these different phases you do not have anybody to guide you, then you will automatically begin to follow your mind. At some point you will fall into confusion and you will not know whether you are doing the right thing. Therefore, the correct thing for one to do is that one should follow someone who has gone through the different phases and who understands the paths of Deen. Such a person will be able to guide one through these different changing phases. In the path of righteousness it takes a long time before a person reaches his goal.
