Question: Why does a Partzuf become “refined” and eject the Light when it receives 20% of the Light and understands that it cannot receive more? Isn’t getting 20% better than not getting anything?
Answer: There are no halfway measures in spirituality: it’s all or nothing. Imagine that you tell your wife that you love her 20%. Can you imagine how she would answer you?
Something like this simply cannot be. In love and bestowal, in giving and in the heart, it is impossible to give part and not the rest. There cannot be compromises here. Compromises can be in everything except for true hatred and true love, which are the Achoraim (back) and Panim (face) of the same adherence.
Question: But we gradually rise and grow. So how is this possible?
Answer: In your gradual ascent, you are always going for broke. You don’t take half or a quarter, rather you invest all of your power or otherwise you won’t rise.
Question: But I am not familiar with the next level.
Answer: This is called going with faith above reason, with your eyes shut. It could be that you will accept 20% of a situation after a calculation, let’s say, Galgalta, but this 20% matches the entire 100% of your powers. If you want to succeed in spiritual advancement or even in corporeal love, without a doubt you need to show that you are giving all of your power to it.
