Krishna lowers the barrier to entry so that no one is excluded. Even if a person does not actively teach or rigorously study, if they simply listen (śṛṇuyād api yo naraḥ) to the Gita, they achieve massive spiritual benefits. The only requirements are that they must listen with faith (śraddhāvān) and completely without envy (anasūyaś ca). Such a person is instantly freed from karmic sins (so 'pi muktaḥ) and attains the highly auspicious, elevated planetary systems where the pious reside (śubhāḻ lokān prāpnuyāt puṇya-karmaṇām).
