Part 4: The Internal and Secret Aspects of Torah You should realize that all of the NaRaNḤaY, of which we have spoken up to now, are in fact five divisions that together make up reality as a whole. For the macro is present in the micro. For example, it is possible [for the individual] to achieve all five aspects of NaRaNḤaY – related to the five general aspects of NaRaNḤaY – even from the inanimate aspect of the spiritual world of Asiya. Similarly, it is impossible to acquire even the light of the inanimate of Asiya without [also acquiring] the [other] four aspects of service [of God], as discussed.
