Charak Puja is a very enchanting folk festival of the Southern Belt of Bangladesh and West Bengal; members of agricultural communities widely celebrate this festival. Charak Puja is devoted to Lord Shiva and Sakti, and people who celebrate this puja have to undergo a long fasting. During this fasting session, the devotees cannot eat from morning to evening and suffers from extreme physical pain. During Charak Puja, people taking up Brata and undergoing fasting, are only allowed to eat fruits and are bound to worship Shiva in order to get his blessings.
The day of Charak is also known as Gajan. On this particular day, stages are made of bamboo. The average height of this stage remains 10 to 15 feet. After, this long fasting session, when it gets over, the devotees get on the stage and start moving forward. On the other hand, knives, glass and thorns are spread all over the ground. Devotees fall on this ground, but are not hurt. It is believed that Lord Shiva has done this miracle by giving them his blessings.
