6.2.46

nātaḥ paraṃ karmanibandhakṛntanaṃ mumukṣatāṃ tīrthapadānukīrtanāt /
na yat punaḥ karmasu sajjate mano rajastamobhyāṃ kalilaṃ tato 'nyathā //

47. For those who seek after Moksha (release from Samsara) there is no instrument to cut the ties of Karma (the root of sin) more efficacious than uttering the name of (than singing the praise of) Hari of hallowed feet, for by virtue of that course alone the mind (of man) does not again get attached to Karma; (but) by any other means the mind continues to be impure through Rajas and Tamas.
