I really struggle with this. Im angry about my mother's death. I don't feel much comfort in thinking she is poured into an indentity-less sea. I miss her dark eyes and skills at haggling and her chicken soup. Yes, her energy is part of my story and all eternity, but yet...where is she? How can we exist if we do not exist separately in a body? How can we have a mind without a brain? A will without hands to execute it? And if oneness is our ultimate destination, how is not also our complete erasure? Why would we want to recognize that prematurely, as in before death? Why not preserve our seperate and created identity for as long as we have opportunity?-- so as to avoid the depressing fate of disappearing? Yes, we are all connected. Energy is recycled. But if I simply understand myself as part of the oneness of hashem, how will i find motivation to accomplish things and enjoy my particular interests...all of this essential to not succumbing to social tyranny?
Balance is key. When you reach the level of a Sadiq then you can worry about this problem your mother's chicken soup sounds amazing and yes she is still here also here and there as we can be both humble nullified and self-actualized
