Offering one's weight of such materials as coconut, coconut water, butter, sugar, fruits, copper, silver, gold or any other material is a popular vow taken by devotees.
The Devaswom will supply most of the materials. There is no advance booking. But for the materials like flowers etc. which may not be immediately available, Devaswom should be informed at least a day in advance or the devotees can bring it. The weighing facilities are available on both sides of the entrance inside the Eastern Gopuram. The expenses involved can be remitted after the offering. For non-Hindus, the thulabharam facility is available near the Kalyana mandapam. Interestingly, thulabharam is offered not only for the human beings but for material processions also. For example, thulabharam is done for movie film rolls with coconut.
