Capital : Capital is the topmost element of a pillar
or column. The crowning animals are masterpieces
of Mauryan art, shown either seated or standing,
always in the round and chiselled as a single piece with
the abaci.

The most visible use of the Ashoka Chakra today is at the
centre of the Flag of India (adopted on 22 July 1947),
where it is rendered in a navy blue colour.

The 24 spokes represent the 24 Jain Tirthankara of the
present cosmic cycle. Alternatively, the 24 spokes
represent the twelve causal links taught by the Buddha
The first 12 spokes represent 12 stages of suffering.
The next 12 spokes represent no cause no effect.

The abacus of an Ashoka Pillar is the carved, drum
shaped base supporting the animal figures (like lions,
elephants, horses, bulls) and Dharma Chakras. It
symbolizes the turning of the Wheel of Law (Dharma)
and represents progress

The shaft of an Ashoka Pillar is its tall, smooth,
tapering, circular main body, typically carved from
a single, monolithic block of polished sandstone
(often Chunar sandstone)
Note: There is no distinct base at the bottom of the shaft.
