Srimad Bhagavatam 9.4.67

9.4.67

मत्सेवया प्रतीतं ते सालोक्यादिचतुष्टयम् । नेच्छन्ति सेवया पूर्णा: कुतोऽन्यत् कालविप्लुतम् ॥ ६७ ॥

mat-sevaya pratitam te salokyadi-catustayam necchanti sevaya purnah kuto ’nyat kala-viplutam

mat-sevaya
by being engaged fully in My transcendental loving service
pratitam
automatically achieved
te
such pure devotees are fully satisfied
salokya-adi-catustayam
the four different types of liberation (salokya, sarupya, samipya and sarsti, what to speak of sayujya)
na
not
icchanti
desire
sevaya
simply by devotional service
purnah
fully complete
kutah
where is the question
anyat
other things
kala-viplutam
which are finished in the course of time

My devotees, who are always satisfied to be engaged in My loving service, are not interested even in the four principles of liberation (salokya, sarupya, samipya and sarsti), although these are automatically achieved by their service. What then is to be said of such perishable happiness as elevation to the higher planeary systems?
