Wangala the greatest traditional festival of Garo had been celebrated at every harvesting period in late autumn in the past. Garo people who were mainly dependent on agro-economy. Garo people do not use any agricultural products before thanking God of fertility Misi-Saaljong. We thank God of fertility, Misi-Saaljong in Wangala through dancing, drinking chu, singing for three day & nights. Since the main occupation of Garo people in Bangladesh is farming and agriculture, we generally worship the Lord of farming and agriculture who bestows us with lots of blessings. The Wangala festival is therefore a grand Carnival to celebrate the harvest season. This is because after years long toil, the inhabitants find relief in seeing the golden harvest. So, we pay homage to the Lord who blesses us with such a splendid crops and sing and dance to offer worship to the great deity, source of unveiled power in this world.
After all Wanna is a Garo festival in every year Garo people celebrate this festival. Wanna is a meeting place of all Garo people.
