Śrīmad-Bhāgavatam · Text 11.13.6
Who is speaking and story frame
सात्त्विकान्येव सेवेत पुमान् सत्त्वविवृद्धये ।
ततो धर्मस्ततो ज्ञानं यावत् स्मृतिरपोहनम् ॥ ६ ॥
sāttvikāny eva seveta
pumān sattva-vivṛddhaye
tato dharmas tato jñānaṁ
yāvat smṛtir apohanam
Until one revives one’s direct knowledge of the spirit soul and drives away the illusory identification with the material body and mind caused by the three modes of nature, one must cultivate those things in the mode of goodness. By increasing the mode of goodness, one automatically can understand and practice religious principles, and by such practice transcendental knowledge is awakened.
