Śrīmad-Bhāgavatam · Text 11.9.12
Who is speaking and story frame
यस्मिन् मनो लब्धपदं यदेत-
च्छनै: शनैर्मुञ्चति कर्मरेणून् ।
सत्त्वेन वृद्धेन रजस्तमश्च
विधूय निर्वाणमुपैत्यनिन्धनम् ॥ १२ ॥
yasmin mano labdha-padaṁ yad etac
chanaiḥ śanair muñcati karma-reṇūn
sattvena vṛddhena rajas tamaś ca
vidhūya nirvāṇam upaity anindhanam
The mind can be controlled when it is fixed on the Supreme Personality of Godhead. Having achieved a stable situation, the mind becomes free from polluted desires to execute material activities; thus as the mode of goodness increases in strength, one can completely give up the modes of passion and ignorance, and gradually one transcends even the material mode of goodness. When the mind is freed from the fuel of the modes of nature, the fire of material existence is extinguished. Then one achieves the transcendental platform of direct relationship with the object of his meditation, the Supreme Lord.
