Incense is burned to worship the nose, and butter lamps are worshiped to the eyes. Tibetan Buddhism also burns incense to worship Buddha. In addition, there is also water and other (food and drink) to worship the mouth. Music is worship for the ears, and flowers are worship for the body. This is an explanation from the "five senses". There may be others that are more detailed. Tibetan families who have the conditions and are careful will light butter lamps at home all year round. Generally, they only light one lamp, and they will increase the number appropriately on special days. For example, on festival days and other days, they will light "hundred offerings" (108 lamps). If possible, you can also order "Thousands of Offerings", "Ten Thousand Gongs", etc. at the temple.
