Sūtra translation
And on account of their (the released) having obtained the fruit, of which it (action) is the cause (means), this state (i.e., performing acts at their pleasure) is but reasonable, as in the instances of the world.
This state, i.e.,-the optional performance or omission of acts by the released souls is also reasonable ; for they have fully achieved the fruit to which duties can lead them ; and this is also a matter of observation in the world, viz., that, after having performed such duties as Vishnu- Kramana forming part of a main act enjoined upon him and accomplished (the latter), the sacrificer may or may not at his will observe it (Vishnu-Kramana).
