As soon as irrevocable loving service is established in the heart, the effects of nature’s modes of passion and ignorance, such as lust, desire and hankering, disappear from the heart. Then the devotee is established in goodness, and he becomes completely happy.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
तदा रजस्तमोभावाः कामलोभादयश्च ये । चेत एतैरनाविद्धं स्थितं सत्त्वे प्रसीदति
tadā rajastamobhāvāḥ kāmalobhādayaśca ye | ceta etairanāviddhaṃ sthitaṃ sattve prasīdati
