The third stage is the service of Torah and mitzvot for its own sake – in order to give [benefit to his Creator], rather than to receive a reward. This service purifies the selfish person’s desire to receive and transforms it into a desire to give. To the extent that the desire to receive is purified, [the person] becomes worthy of and prepared to receive the five parts of the soul referred to as NaRaNḤaY (as discussed below, chapter 43).
The [five parts of the soul] want to give, but they cannot become enclothed in the body (see above, chapter 23) while the desire to receive controls the body, since the desire to receive stands in an oppositional relationship to the soul, or at least it [the desire to receive] is different in form [from that of the soul]. For the matters of enclothing and equation of the form work together (above, chapter 11).
When a person becomes worthy and he becomes only a desire to give, wanting nothing for himself, he has equated his form with the higher aspects of NaRaNḤaY. (The NaRaNḤaY extend from their source in the Ein Sof, from the situation of unity, through the sanctified worlds of ABYA.) They [NaRaNḤaY] will flow to him, and will be enclothed in him, one at a time.
