During the early days of the ashram, I used to be Swamiji’s personal secretary and also taking care of His personal seva.
On multiple occasions, after Swamiji gave energy darshan to large crowds during some program, I have noticed sandal fragrance coming from Swamiji, and also from the clothes used by Him, while taking them out for washing the next day.
At that time I don’t know that this is also a special siddhi that is manifested by Avatars!
