Better is truly the conquest of self than that of other people. For one who is self-disciplined and always lives with self-control,

Attā have jitaṃ seyyo — better is truly the conquest of self: have is an emphatic particle. Without doubt, truly. Repetition of the theme from the previous verse with greater emphasis.

Yā cāyaṃ itarā pajā — than the conquest of other people: conquering others can bring power, wealth and fame. Conquering oneself brings liberation. The hierarchy is clear and irrevocable.

Attadantassa posassa — for one who is self-disciplined: attadanta is one who has tamed their own self. The same term as in verse 80 where artisans “shape” their materials. One’s own character is the material the practitioner works with.

Niccaṃ saññatacārino — who always lives with self-control: discipline not as occasional repression but as a continuous way of life. This verse leads directly to the next (105) which completes the image.
