Devotees are not interested in liberation

SB 9.4.67
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 planetary systems?
