If you would like to improve your ability to smell, here's a pleasant exercise.  Take a few seconds to relax and sniff the air wherever you are to discover what odors may be around you.  Try this exercise in a restaurant or in your kitchen.  Open a few containers of spices such as cinnamon, cumin or basil and sniff them.  Sniff whatever foods you may have in your refrigerator.  Sniff the air when you are putting gas in your car.  When you identify odors, mentally tell yourself what you are smelling.  Say something like,"I am sensitizing my sense of smell for use in my psychic development and I am currently smelling (name the odor).'  You will probably be surprised to discover the many subtle as well as pungent odors you encounter every day.  Source: Psychic Development for Beginners.  by William W.
