Four levels of acceptance

It’s been intimated that a disciple should anticipate the guru’s order or carry it out cheerfully, and that this is better than reluctantly carrying it out, or not doing it all. Looking for what Srila Prabhupada might have said on this topic, this is what I came up with: “A son who acts by anticipating what his father wants him to do is first class, one who acts upon receiving his father’s order is second class, and one who executes his father’s order irreverently is third-class, and one who refuses his father’s order is like his father’s stool.” (Translation to SB 9.18.44)
