forgetful - - since our entire presence / aura is one of vibration - - if we carry the sense of humility and kindness within ourselves - - that will be felt by others. This would be difficult to do if we just "felt" these (and other) qualities sporadically. They must be a part of the individual - - and that individual would truly live from that perspective.
There are most certainly Masters that live within these qualites - - and much greater. There are countless others that have yet to attain true and real Mastership that can do the same. It is the quality of humility / kindness / sincerity / etc. that exudes this. Not necessarily a status - - tho one kinda goes with the other.
And yes - - they can exude an aroma. Due to the fineness of vibration of aroma's - - we can sense a lot this way. Certain Masters can be detected by their distinct fragrance.
You might wish to consider - - that it is not necessarily the ability of the Master to make His presence known that is important here. It is *our* ability to detect that presence. It is up to us to detect. It is not necessarily up to a Master to reveal. Unless and until we are ready.
Sure - - some people can get somewhat "addicted" to the feeling that "comforting presence." It would actually be a good learning experience for Soul at that point on the Path. Nothing "wrong" with that. Soul has LOTS of time to figure all of this out.
