If one is very serious about liberation, he must stick to the process of transcendental loving service, engaging twenty-four hours a day in the highest stage of ecstasy, and he must certainly be aloof from all activities of sense gratification.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
विरक्तश्चेन्द्रियरतौ भक्तियोगेन भूयसा । तं निरन्तरभावेन भजेताद्धा विमुक्तये
viraktaścendriyaratau bhaktiyogena bhūyasā | taṃ nirantarabhāvena bhajetāddhā vimuktaye
