Kill the Buddha:
I see the Buddha more as a symbol than an actual dream character. Most, if not all of the sayings attributed to him where the work of those who only new of him via the oral tradition. Bottom line is take anything that is of value to you on your journey, and there certainly are some useful quotes attributed to him, and promptly discard that which doesn’t appear to take you further.
I suggest you view the Buddha as a pointer and finding him on your path as an opportunity to realize that you are looking outside for what it inside. Of course, it's all ''inside'' but that is a significant realization all by itself. Your path is yours and distinct from anyone else's. If something/someone takes you further, go for it, if not then I suggest you promptly discard them and find something that works for you.
The Zen master Seung Sahn is reported to have told his students that there are three things they have to do; kill their parents, kill the Buddha and finally kill their master…. himself. Of course we are speaking metaphorically here, and it is a deep topic.
What I experienced in my own life and seen in many of my students is there is no need to kill anyone. If there would be anything one should kill, it's their stories about what and who those above mentioned three character(s) were/are... what they mean to the student. This is not that difficult because upon seeing stories clearly for what they are (ALL stories are fiction) they will disappear of their own accord… another example of the power of awareness.
Why will the story of ''parents'' fall to the wayside? Eventually you will find that those well meaning people had no training in how to raise a child to adulthood. They had numerous weakness and challenges and their parents taught them precious little. In reality, most of what your parents were taught was counter to H/A and general happiness. Proof abounds around us.
In the formative years every child views their parents as Gods because they were the source of food, attention, shelter and wellbeing. The story of perfect parents or terrible parents is just a story. They were neither. Perhaps they are best thought of as well intentioned care givers on a 20 year contract (more or less).
Killing the Buddha is simply dropping all pointers, all metaphors, all stories, all teachings… and realizing the Buddha is/was ONLY a finger pointing at the moon and only required until one looks and sees that moon. No need to keep looking back at the finger. Beyond that there is the realization that you are the Buddha, the finger and the moon.. all is within you. By this realization the story of Buddha will dissolve on its own.
