If there is a truth we have to move towards it. If there is a right way to live, we must seek to embrace it. If there is a right and wrong, then we are morally required to seek the right way out. All that is bad is of one substance and all that is good is of a different substance. To live right and to avoid evil we have to follow one rocky and narrow path, it is the way of Asceticism. There is no other way or other path that leads to the truth.
