>I have a single purpose and deviating from what I've been told to do is unacceptable
A slave who fully knows and internalizes her place is somewhat of a rarity, at least enough that she never falters in her devotion to being nothing but what her Master wills.

slaves do need sight for a lot of things. To clean Master's home and cook his meals, for one. When attending to him personally, having sight helps in being in tune with his emotions to make him happier, but there are situations where sight is not needed, and thus would be best taken away.

Punishment is the obvious one. Taking away a slaves unnecessary sight would actually likely heighten the pain. Sleeping too would be a good fit, although if a slave has a routine of preparing herself early before waking up Master she needs her sight for that, and I don't think its right to permit a slave to remove her own blindfold.

>my life is duty
Your life is duty, a duty towards service, towards devotion, towards being shaped into whatever your Master wishes.

Such words would be good for affirming prayers for slaves. Your life was never yours, and all you ever had to worry about was living up to the life that your Master had chosen for you to live.
