Afterwards this overall whole must be differentiated into its detailed parts... Clearly, this is always the way of gradation: first there is the overall whole, and afterwards this whole divides up into its constituent parts....and the embryo is not revealed on its own until it displays all its constituent parts fully revealed. Since we are following the path of gradation, the fact is that no light can carry out its functions until all its constituent parts are revealed in it. (The path of gradation requires first the overall whole – through coupling – and afterwards the details – which develop during the pregnancy.)
For all those parts are necessary in order to produce the required function. Thus as long as it has not reached this point, we cannot count it among the governing powers (i.e. as a Partzuf in itself).
