People burn incense, and give other offerings, such as food, flowers, and money to the Gods within the temple and pray to the statues.
You would think the temple was on fire, but no, don't be alarmed, the people hold sticks of incense while they pray, thinking that the smoke carries their prayers up to the Gods. When they are done praying, they stick the incense into one of those huge pots that is filled with sand. Very smoky.
This is inside the courtyard of the temple. A very busy place!
