We can make the traditional offerings of a ritual of symbolic or mental worship using gestures to stand for actual physical acts of generosity. Usually, the mudras work to enhance or underscore the acts of generosity. Some believe they have an actual effect on the environment in a way that is similar to mantras.
The traditional offering mudras are
1.argham -- water to refresh the mouth (Pouring a beaker.)
2.padyam -- water to refresh the feet (A basin.)
3.pushpam -- flowers for delighting the eyes (Two blossoms.)
4.dhupam -- incense for clearing and perfuming the air (Sticks of incense.)
5.alokam -- light to brighten the space (Two waving lamp wicks.)
6.ghande -- scented washing water (Parting a cloth.)
7.nevityeh -- refreshment (The universal sign that indicates a display set out.)
8.shabda -- music to delight (Clashing a pair of cymbals.)
