It is worth mentioning that desire and necessity are in line (related) with each other in many cases, with desire exceeding necessity in most instances, while equilibrium is a point where both are cooperative before diverging from each other.
From The Equilibrium of Desire and Necessity.
The Needs include food, shelter, clothing, organizational tasks, peace and security etc.
From The Unjustified Burden and Its Implications.
To respect the natural cause of an event means to keep in view why nature has placed that event in us (e.g. hunger is there to keep the body alive), and to fulfil it for that very purpose, i.e. as far as the necessity goes, rather than turning it into a pursuit of desire.
From The necessity basket.
