What Is the Purpose of Creation?
…His guidance is purposeful and aims to eventually bring us [our souls] to adhesion [similarity] with Him, so it would reside within us [within our corrected desires, in full equivalence with the property of bestowal and love called the Creator]….
– Baal HaSulam, Article “The Essence of Religion and Its Purpose”
…the purpose of instilling the soul [the point in the heart] within the body [desire to receive] is so that the soul, being precisely in the body [to receive in order to bestow], returned [became similar] to its root [the Creator] and merged [in complete similarity] with the Creator, as it says: “(1) And love thy Creator, (2) and walk His ways, (3) and keep His commandments, (4) and merge with Him.”
– Baal HaSulam, Igrot (Letters) pg. 63
Every person is obliged to attain the root of his soul.

It turns out that the purpose of the whole Creation is that the lowly creatures will be able, by keeping Torah and Mitzvot [Torah is the Light of correction, and the Mitzvot are the corrections of man’s 613 egoistic properties which are performed by the Light. The soul is the desires of bestowal, a soul’s qualities of bestowal toward other souls], to rise ever upward, ever developing, until they are rewarded with Dvekut with their Creator.
