It is the verdict of all śāstras and great personalities that service to a pure devotee is the path of liberation. By contrast, association with materialistic people who are attached to material enjoyment and women is the path of darkness. Those who are actually devotees are broadminded, equal to everyone and very peaceful. They never become angry, and they are friendly to all living entities.
