Puri (Odisha):The holy temple town of Puri known as 'Nilachala Dham' is situated on the shores of the Blue Ocean (Bay of Bengal). Lord Sudarshan, also known as 'Chakraraj', the symbol of Lord Vishu’s discus, is beautifully placed on a blue wheel on the top of the grand temple of Puri or 'Purusottam Khetra' which is located on a blue hill and happens to be the abode of Supreme Lord Jagannath.
This 'Nilachakra' is extraordinary, attractive and magnificent because of the presence of a flag known as 'Patitapabana Bana' flying on its mast. This flag is called "Patitapabana Bana" because it is regarded as the saviour of the sinful persons.
The uniqueness of this 'Patitapabana Bana' of the Supreme Lord Jagannath or 'Purushottam' is shrouded in mystery like the mysterious Lord Himself. This flag flies in the direction opposite of the wind. As per the tradition, the colour of the flag is white, red and yellow. The shape of the flag is triangular and in its centre, there is a figure of the moon looking upwards and a figure of Sun God within it.
As per the rituals, it is forbidden to keep the same flag flying for more than one day. Every evening the old flag is brought down and a new flag is fixed on the 'Nilachakra'.
