could be you need to be more passionate, but it sounds like you need to express your emotions honestly since this is a spiritual person. it doesn't mean you have feelings for this person [perhaps reflect on the person and what you admire about them, it could be things you wish you could have as well]
now, by 'very spiritual' is he a spiritual leader? that could effect the meaning, but it probably represents wisdom and enlightenment. the phrase 'playing with fire' and the person could be your subconscious trying to shock you into a realization. is there a person in your life influencing you negatively? it could be a warning, like you admire to be like this person but by following the other individual you might get burned.
