The constraint (Gevurah)
#sefirot/gevurah
That it takes an infinite amount of energy to produce a finite packet of energy is an expression of constraint (tzimtzum) inherent in this world—which is essentially a world of limits. Because in order for the finite to emerge from the infinite, the infinite has to constrain itself! Creating a world in which the finite expresses itself is an expression of the finite inherent in the infinite.
Any form of order requires constraint.
Power exchange (Chesed & Gevurah)
#relationship
Another view of mercy as the infinite constraining itself to become finite, to allow the finite to exist. Constraint being another aspect of Love.

And love always has an element of power (or energy). We speak of the power exchange inherent in all relations, because in order for there to be any relationship, or flow of energy, there has to be a difference, an energy differential between the two interacting elements, else there can be no exchange.
This becomes a journey that is an exploration of power in merciful love and love in power: Chesed & Gevurah
