You are perfect and complete, so abandon the idea of incompleteness. There is nothing to be destroyed. Ahankara, the individual 'I', is not a real thing. It is the mind that makes the effort and the mind is not real. Just as it is not necessary to kill a rope that one imagines to be a snake, so also there is no need to kill the mind. Knowing the form of the mind makes the mind disappear. That which is forever non-existent is already removed.
