7.15.25

रजस्तमश्च सत्त्वेन सत्त्वं चोपशमेन च । एतत्सर्वं गुरौ भक्त्या पुरुषो ह्यञ्जसा जयेत् ॥ २५ ॥

rajas tamas ca sattvena sattvam copasamena ca etat sarvam gurau bhaktya puruso hy anjasa jayet

rajah tamah
the modes of passion and ignorance

indeed
anjasa
easily
jayet
can conquer.

One must conquer the modes of passion and ignorance by developing the mode of goodness, and then one must become detached from the mode of goodness by promoting oneself to the platform of suddha-sattva. All this can be automatically done if one engages in the service of the spiritual master with faith and devotion. In this way one can conquer the influence of the modes of nature.
