The preperation of Simpua (ritual incense) is one of the traditional arts of Tibet. This incense is composed of 35 different spices and aromatic substances of which nagi, saffron, red & white sandalwood form a part. The excellence of Zimpua, however, is not merely in the purity of it's ingredients, but in the manner of it's formulation as well. It is prepared with great care and in accordance with the traditions preserved through the centuries within the monastic orders of Tibet.
