It isn't possible to kill part of your “self” unless you kill yourself first. If you ruin your conscious personality, the so-called ego-personality, you deprive the self of its real goal, namely to become real itself. The goal of life is the realization of the self. If you kill yourself you abolish that will of the self to become real, but it may arrest your personal development inasmuch it is not explained. You ought to realise that suicide is murder, since after suicide there remains a corpse exactly as with any ordinary murder. Only it is yourself that has been killed.
Carl JungWe should not pretend to understand the world only by the intellect. The judgement of the intellect is only part of the truth.
Carl JungWhenever there is a reaching down into innermost experience, into the nucleus of personality, most people are overcome by fear and many run away. . . The risk of inner experience, the adventure of the spirit, is in any case alien to most human beings. The possibility that such experience might have psychic reality is anathema to them.
Carl Jung
