a) the want to hold onto tempts others to want what one holds onto aka greed breeding envy.

b) only suggestion tempts consent, while perception demands adaptation. Only nature offers perceivable, whatever others are suggesting tempts one to ignore that.

Suggested Pepsi (want) vs Coke (not want) tempts one to ignore adapting to perceivable thirst (need). It doesn't matter who makes the suggestions; what they're suggesting or which side one chooses to consent to...only resisting suggested (want) for perceivable (need) sustains matter.
