A sacred pot, Bhumchu contains holy water which is blessed by Ngadak Sempa Chenpo after he said the Mane Mantra five billion times. The amount of water in the Bumchu is said to predict the fate of Sikkim for the whole year. If it is seen that the Bumchu is full to the brim it signifies that the year will be a year of revolutions and turmoil. On the other hand if the level of the water is low then the year will be affected by ailments and diseases. However if the Bhumchu is half full, then the year will be a prosperous one.
It is seen over ages that the holy water has not dried up or has got spoiled in more than 300 years. It still smells fresh. Bhumchu Festival attracts thousand of devotees from Nepal, Bhutan, Darjeeling and other neighboring places. It is celebrated at the Tashiding Monastery. During the Bumchu Festival, lamas of the monastery open the Bumchu for the public display which is otherwise locked. Some of the holy water is distributed to the devotees after which the Bhumchu is again sealed to be opened next year.

Holi, the festival of Colours is celebrated in different corners of India with pomp and gaiety on full moon day in the month of Phalgun which is the month of March as per the Gregorian calendar.
