when we are burning any thing generally the body releases some gases and especially carbon di oxide and carbon monoxide.
and in some systems( organic) sooty nad non sooty flames are there.if we observe flame with black smoke it is sooty and if the flame is without that black smoke it is non sooty.
so,the gases which are released causes the flame to go up.
as it contains hot gases which are with low density ,they will go up.

The flame consists of the by-products of combustion for the item being burned (oxidized) in a very exited state (release light). Generally, these are water vapor and carbon dioxide plus oxides of nitrogen and unburned hydrocarbons. These have mass but a density considerably less density than the surrounding air. In other words they want to "float" upwards just as a piece of wood submerged in water bursts upwards when released.

Flame raises upward can be viewed as an analogy!.
Aspirations=Flame
Aspirations shld always be high, we have to aspire to reach our level best, top. This is taught by Flame, which always goes upward.

Flame has no mass,so it is lighter than air, so according to laws of density it goes upwards.

Burning gives off heat,heat warms the air around the burning object,warm air rises and cold air sinks creating thermal currents.
The warm rising air carries the flame up with the air currents.

the elements of fire is lighter than the air floating around on the earth.. its like a ballon filled with helium will go up. but if somebody farts.. .. haha. farts gotta different densities , if you know what i mean...
