Lord Sri Chaitanya Mahaprabhu was born in  Sridhama  Mayapura,  Navadvipa in Bengal, on the phalguni purnima of the year 1486. Born as the son of a learned brahmana,  Sri  Chaitanya   Mahaprabhu was known as Nimai Pandit in his youth due to his unrivalled mastery of the Sanskrit  language  and  the  Vedic literature :
There was opposition to the movement of Sri Chaitanya Mahaprabhu. On the one hand many so-called Hindus objected to the fad that be engaged everyone in chanting the holy name of the Lord without discrimination of caste, religion or social position; on the other hand, the Mohammedans felt that his processions were a threat to their social and political domination. In spite of all such obstacles, however, Sri Chaitanya Mahaprabhu established the fact that there is a universal religion for developing love for the one Supreme Lord who is the supreme controller of everyone and everything.
The advent of Chaitanya is marked as the beginning of a new era in Bengal. The birth of the cult and  the  spirit  of  the Renaissance, almost synchronized with his arrival. The growth of vernacular literature in Bengal got a new fillip with his appearance. Beyond everything, Chaitanya Mahaprabhu was a great lover  of humanity. He was  a  friend  of  the poor and the wretched. His heart was always full  of love  and  sympathy for them.  As a great  solace to the  suffering  soul  and a healer to the bereaved,  he  proved himself strongly anti-communal and a life-long denouncer of untouchability and casteism.
The Department of Posts is happy to issue a Commemorative Stamp on the great Saint Chaitanya: Mahaprabhu's 100th birthday.
