The Yoga of Liberation by Renunciation

Krishna gives assurance about the power of hearing this teaching. 'Śraddhāvān anasūyaś ca śṛṇuyād api yo naraḥ'—and (ca) even (api) a person (yaḥ naraḥ) who hears (śṛṇuyāt) this with faith (śraddhāvān) and without envy (anasūyaḥ). 'So 'pi muktaḥ śubhāṁl lokān prāpnuyāt puṇya-karmaṇām'—he (saḥ) also (api) will be liberated (muktaḥ) and will attain (prāpnuyāt) the auspicious worlds (śubhān lokān) of those who perform meritorious actions (puṇya-karmaṇām). This is the assurance: even just hearing this teaching with faith and without envy leads to liberation and attainment of auspicious worlds. You don't need to be a great scholar or practitioner—even hearing with faith and without envy is enough. This reveals the power of the teaching: it's not just the teaching itself, but hearing it with the right attitude (faith and without envy) that brings liberation.
