Here is a possible analogy for the "completeness" of pleasure:
A meal served without something to drink would be considered incomplete...
"a meal" = all the many varied pleasures of life
"something to drink" = removing fears of death & gods and adding in prudence (the correct understanding of choices and avoidances).
So altogether these would make a "complete meal" which would be an analogy of a complete life of pleasure and well-being.
