My devotees, who are always satisfied to be engaged in My loving service, are not interested even in the four principles of liberation [sālokya, sārūpya, sāmīpya and sārṣṭi], although these are automatically achieved by their service. What then is to be said of such perishable happiness as elevation to the higher planetary systems?
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
मत्सेवया प्रतीतं च सालोक्यादिचतुष्टयम् । नेच्छन्ति सेवया पूर्णाः कुतोऽन्यत्कालविद्रुतम्
matsevayā pratītaṃ ca sālokyādicatuṣṭayam | necchanti sevayā pūrṇāḥ kuto'nyatkālavidrutam
