Yes, I agree with @SubClubHouseMafia also.
Seems to me that there are at least two parts to Aura projection.
One part is your underlying condition. Your various levels of vitality and your various characteristics.
The other part is your ‘Openness’.
I think of a room with a bright lamp shining inside. The lamp and its brightness represent vitality, energy, health, etc.
But the doors and the windows of the room may be opened or closed. The shades on the windows may be black, or translucent or transparent.
The point is that whether by choice (for example, the ‘nonleaking’ practices of brahmacharya) or by nature (for example, a restrained, repressed personality) a person’s energy may or may not radiate and shine out as much.
I suspect that in addition to shaping the brightness of one’s light, the aura subliminals also influence one’s openness or willingness to let it shine.
