A gurmukh finally is one who has attained gian, or true knowledge. He consciously acts for the weal of others, even of those who bear him ill will.” “Manmukhs, on the contrary,” continued the Guru, “are those egoridden persons who forget the good turn done them, but do not ever forget the injury inflicted upon them. Worse are those with malice towards all, good or evil. The worst are they who return evil for goodness. They are immune to the teaching of the Guru.” Bhai Bhulla and his companions, enlightened by the Guru`s precept, continued to serve the sangat with devotion.
