Scent is particularly useful for associative learning, so if you want to put yourself in a consistent energetic place selecting and repeatedly utilizing a scent will be very effective for your practice and vibes. Our scent processing is actually directly connected to limbic structures that process emotion (the amygdala) and associative learning (the hippocampus) as stated by Assistant Professor of Psychology Rachel S. Hertz of Brown University in the Scientific American article called ‘Do Scents Affect People's Moods or Work Performance’. Make sure it is a pleasant smell, since a good smelling scent will boost your mood and creativity. Again, these are the things we need to get those vibes high and your mind open. Also, consider a smell that is not only pleasant but also with as little emotional or memory attached that you can find, so you can start fresh with an odor with a clean slate- ready for you to create the connection between it and the intuitive, psychic, medium, healing process and connective state.
