The outer offerings are represented by seven water bowls according to Indian custom. The fourth offering is incense which represents morality and leads to a favorable re-birth in the human and deva realms. You can also use saffron water in place of the first two offerings. The seventh is food. In Tibet we usually mix tsampa with butter, milk, cheese and the three sweets - brown sugar, white sugar and honey.
Music is the eighth offering.
The inner offerings on the shrine are men, rakta and torma. Men is nectar and is placed on the shrine s right-hand side.

Dutsi has many functions, such as appearing as light which invokes wisdom or transforming into a hook catches siddhis and so forth. Rakta is placed on the shrine s left-hand side.
