Of all Dhupas of the Sari class, the Aquilaria Agallocha is the best. It is very acceptable to the Yakshas, the Rakshasas, and Nagas. The exudation of the Boswellia serratta, and others of the same class, are much acceptable to the Daityas.
अगुरुः सारिणां श्रेष्ठो यक्षराक्षसभोगिनाम्। दैत्यानां सल्लकीयश्च काङ्गतो यश्च तद्विधः॥
