Why Did the Creator Place the Burden of Creation Upon Us?
The first rule of what we know regarding the intention of the Emanated is that He desires to do good, He desired and created those who would receive His goodness. In order for the goodness to be complete, it has to be merited, not as charity, so shame would not taint it, as one who eats that which is not his.
In order for them to be able to merit [instead of created beings, to become independent, to become similar to Him], He created [especially for them] a single reality [corrupted by Him] through which they may be corrected, which He does not need, rather by their correction [which they perform themselves] – they will merit [to become independent like He].
– Ramchal, Klalei Pitchei Chochma ve Da’at (The Rules of Gates of Wisdom and Knowledge)
This is the rule, The Lord limited himself, meaning that He limited His ability [perfection], not to create them to the extent of His force [make creation perfect], but rather in accordance with what He desired and His direction. By creating them [purposefully, by restricting Himself, His perfection, His revelation by effort] lacking, in order for them [have an opportunity] to complete themselves by themselves [until reaching perfection, His level, similarity to Him], their completion [attained by themselves] would be their [merited] reward, resulting from their efforts to attain Him. And all that [evil created by the Creator and an opportunity to turn it into good] only serving His desire to do complete goodness [to the creatures].
– Ramchal, Da’at Tevunot (Knowledge of Wisdom), Item 28
