“Kill your idols” seems like a very “far off” applicable phrase. It belongs to a concept outside ourselves, something to adjudge in the field of someone we admire in a fantasy world or referential world.
Instead I feel like we should use it more “inwards”. Never idolize past versions of yourself. Allowing space for transformation does require some sort of death. But prolonging the grief of a particular version of who you’ve been, turns the beauty and presence of natural change into suffering. Try not to fool yourself into thinking that every dying part of who you’ve been needs to be grieved. This could become an excuse for you to hold onto an idealization . This grief will not be a way to honour yourself. It can easily become a way to erase yourself instead.
