In plain words
So he who gives ostentation no room, lets no Ahaṅkāra come near, and moves humble and obedient, is the one who seeks the good of the world. The country will prosper only when people prosper by holding that “the good of the world is the good of the individual”. The true student must keep the good of the world as his aim and take the vow of helping others in simplicity. This is right Vidyā.
