Those who go farther, their moral is to overlook all they see on their way, as their mind is fixed on the goal. It is not a sin to know anybody's thought, but it is a fault no doubt if one professes to do so. To try to know the thought of another for one's own interest is not just nor beneficial; at the same time to sit with closed eyes is not good either. The best thing is to see and rise above, never to halt on the way, and it is this attitude that, if constantly practiced, will lead man safely to his soul's desired goal.
