Aloha Oxygen,
Good to hear from you again.
The "burning smell" or "smoke" thing is common, expecially when working on others as you're turning the blockages to smoke.
As for the "perfume," it could be a lot of things, including the master's energy. Are you walking around Macy's in your meditation when smelling ?

There will be all sorts of experiences you may have and continue having, or it may be for a brief time during your practice. I remember after finishing a Level Three retreat when I first started smelling the people I was going to come in contact with. I was running housing for a university at the time and each phone call I recieved that day was perfaced with a smell - specific blockages, a perfumehe was wearing, the alcohol he had been drinking, etc.
Much Love, Shawn
